Uniform Type Identifier Issue

Update: I’m not sure how or why, but the app is now opening when airdropping the file.

I’m having some trouble pinning down an issue when importing a backup file. I have a UTI set up. Airdropping the file used to open my app for importation, but for some reason I’m now being told that importing it requires installing my app from the App Store (it isn’t in the App Store yet), or I can save it to the Files app. When saved to the Files app it will open my app locally, but for some reason it isn’t being recognised as present when airdropping I suspect it might be a naming issue, but I’m a bit stumped. Any ideas?

Cheers.
