[Bug]: Unsharing is not possible when maps are enabled

⚠️ This issue respects the following points: ⚠️

Bug description

When maps is enabled, after sharing a document, unshare is not working/possible.

This has been observed by others and found out that that this package was the culprit from Reddit.

Steps to reproduce

1. Enable maps
2. Share a document (either public or email)
3. Unshare a document

Expected behavior

I expected the share to be removed.
