Web Share API is not working when button is clicked

Question

I am trying to use the web share API in order to allow users to share the links of article URLs. I want it to be that when a user clicks on the "Share Article" button, the user receives multiple social media and apps that they can share to and when they select the preferred app it sends the URL that I have provided. Im not sure what the issue is, I run the website on GitHub pages but I don't believe that is the issue. Any suggestions or solutions? I will add the code below.
