Selenium python how to upload file when there is no input type file?

Question

I am using Selenium python to automate a site. The problem I have face is, I have to upload file but there is no input type file available where I could have been using send_keys() method. The File upload element:

<div id="data-assets-interior-file-upload" data-upload-properties="{&quot;formId&quot;:&quot;form-main-1&quot;,&quot;path&quot;:&quot;data[assets][interior]&quot;,&quot;modalUpload&quot;:&quot;Uploading...&quot;,&quot;warnExtensionsStrings&quot;:{&quot;pdf&quot;:&quot;&lt;div class=\&quot;a-box a-alert-inline a-alert-inline-warning\&quot;&gt;&lt;div class=\&quot;a-box-inner a-alert-container\&quot;&gt;&lt;i class=\&quot;a-icon a-icon-alert\&quot;&gt;&lt;\/i&gt;&lt;div class=\&quot;a-alert-content\&quot;&gt;\n            Most PDF files do not produce great results in an automated conversion process. We recommend using a Word, Mobi, ePUB or HTML file if you have one. &lt;a href=\&quot;\/en_US\/help\/topic\/A2GF0UFHIYG9VQ?ref_=_fg\&quot; target=\&quot;_blank\&quot; rel=\&quot;noopener noreferrer\&quot;&gt;Learn more.&lt;\/a&gt;\n         &lt;\/div&gt;&lt;\/div&gt;&lt;\/div&gt;\n         &lt;div id=\&quot;file-warn-actions\&quot; class=\&quot;a-form-actions a-spacing-none a-spacing-top-large\&quot;&gt;\n            &lt;div class=\&quot;a-row a-spacing-none\&quot;&gt;\n            &lt;div class=\&quot;a-column a-span6\&quot;&gt;\n               &lt;span class=\&quot;a-declarative\&quot; data-action=\&quot;potter-file-warn-extension-continue\&quot; data-potter-file-warn-extension-continue=\&quot;{}\&quot;&gt;\n                  &lt;span id=\&quot;file-warn-extension-continue\&quot; class=\&quot;a-button a-button-base button-fill\&quot;&gt;&lt;span class=\&quot;a-button-inner\&quot;&gt;&lt;button id=\&quot;file-warn-extension-continue-announce\&quot; class=\&quot;a-button-text\&quot; type=\&quot;button\&quot;&gt;\n                     Continue with PDF\n                  &lt;\/button&gt;&lt;\/span&gt;&lt;\/span&gt;\n               &lt;\/span&gt;\n            &lt;\/div&gt;\n            &lt;div class=\&quot;a-column a-span6 a-span-last\&quot;&gt;\n               &lt;span class=\&quot;a-declarative\&quot; data-action=\&quot;potter-file-warn-extension-cancel\&quot; data-potter-file-warn-extension-cancel=\&quot;{}\&quot;&gt;\n                  &lt;span id=\&quot;file-warn-extension-cancel\&quot; class=\&quot;a-button a-button-primary button-fill\&quot;&gt;&lt;span class=\&quot;a-button-inner\&quot;&gt;&lt;button id=\&quot;file-warn-extension-cancel-announce\&quot; class=\&quot;a-button-text\&quot; type=\&quot;button\&quot;&gt;\n                     I have another format\n                  &lt;\/button&gt;&lt;\/span&gt;&lt;\/span&gt;\n               &lt;\/span&gt;\n            &lt;\/div&gt;\n            &lt;\/div&gt;\n         &lt;\/div&gt;&quot;,&quot;pdf-header&quot;:&quot;Do you have another format?&quot;},&quot;acceptedExtensions&quot;:&quot;doc,docx,zip,htm,html,mobi,azw,epub,rtf,txt,pdf,kpf&quot;,&quot;multipart&quot;:null,&quot;persistSuccess&quot;:true,&quot;warnExtensions&quot;:[&quot;pdf&quot;],&quot;key&quot;:&quot;save&quot;,&quot;url&quot;:&quot;\/en_US\/title-setup\/kindle\/A3U1YUNVSBYTMZ\/content\/action\/save&quot;,&quot;workflowId&quot;:&quot;assets.interior&quot;,&quot;assetType&quot;:&quot;DIGITAL_BOOK_BLOCK&quot;}" class="a-section jele-file-field">

Can anyone let me know, how to handle this scenario? If you are gonna recommend me some other library for it then please post relevant examples in python as well. Thank you
