title: Google Docs/Slides add-on: other users need to request access when installing from marketplace
body: <p>Summary: when other users find my Google Slides add-on in the Google Workspace Marketplace and try to install it, they hit a screen saying they need to request access. When they click the button to request access, it sends me (the script owner) a request to share the script file, which should not be necessary. How do I fix this?</p>
  <hr />
  <p>I have a Google Slides add-on which has been publicly listed in the marketplace for years (predating the rebranding to Google Workspace). I last updated it in 2019, and recently I wanted to publish another update.</p>
  <p>Since this is an old project, I had to go through migrating the add-on to its own standard GCP project and then getting OAuth verification for the (not very sensitive) scopes it needed. This is all done now. All throughout, the add-on has continued being listed in the Google Workspace Marketplace, even though no new users could use it.</p>
  <p>All that is done, but other users are still unable to install the add-on from the Marketplace. Now, when they try to do so, they'll get a small new window pop up saying they need to request access - seemingly to the script file of the add-on. This shouldn't be necessary. Does anybody know why it's happening?</p>
  <p>If you want to try yourself, the add-on is called Superuser Tools, and the Marketplace listing is <a href="https://workspace.google.com/marketplace/app/superuser_tools/520954176163" rel="nofollow noreferrer">here</a>.</p>
