Collaboration not working ('grant access' button inactive)

[oolong]

Describe the bug
When I click on 'grant access' it does nothing at all. I can't see any sign of an error in the console, or anything.

Wasn't it possible to just share a link to a Gingko tree, before?

To Reproduce
Steps to reproduce the behavior:

1. Go to a tree
2. Click on share button
3. Enter address
4. Attempt to grant access

Expected behavior
It should say whether it's granting access, and hopefully do so

Software info:

• Linux, Ubuntu Core 24; Opera 133.0.5932.85 and Chromium 149.0.7827.196
• Gingko web Version

Thank you!
