Not sure if researchgate is still a thing. I had it and uploaded all my papers there. They show up automatically on Google. I believe this is allowed since you’re allowed to share copies of your publication on your website.

The problem is my researchgate account was connected to my academic account. It’s been a while since I graduated so I’ve lost access to my own publications and page.

But I used to use researchgate and requests in researchgate quite a bit.

indeed... and use Zotero with the correct plugin to download them automagically
