easily you can use (a) tag in css :
<a href="https://docs.google.com/forms/d/e/1FAIpQLSdupUHV2uO6q69BHXvPzE1DgJu32HYQ31zPdyZ5uflmOftXRw/viewform" >
Text to show in your link
</a>
and if you want your link seems like buttons you can use this code with styles:
<a style="display: inline-block; padding: 6px 12px; margin-bottom: 0; font-size: 14px; font-weight: 400; line-height: 1.42857143; text-align: center; white-space: nowrap; vertical-align: middle; -ms-touch-action: manipulation; touch-action: manipulation; cursor: pointer; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; background-image: none; border: 1px solid transparent; border-radius: 4px;color: #333;background-color: #fff;border-color: #ccc;" href="https://docs.google.com/forms/d/e/1FAIpQLSdupUHV2uO6q69BHXvPzE1DgJu32HYQ31zPdyZ5uflmOftXRw/viewform" >
Text to show in your link
</a>
Its better to copy <a>
style content in to your css file.
If you want change color of button just change background-color and color in <a>
style.
