Hey @vpukhanov,
Just to clarify, to access $HOME/.git (or any other top-level hidden data directories within a user’s real home directory) you should use the personal-files interface.
This recent similar post can be of help to move fw with your request Auto connect / alias request for mob-sh. Please note your declaration should follow the expected format (i.e., the interface reference should be named dot-git etc).
Once you have your snapcraft updated (move from classic to strict confinement + add the required interfaces), upload a new revision to the store and let us know so we can proceed with the approval process.
Thanks!
