I'm aware of how to set up chat backups on Android, but this only makes local backups that you have to manually upload or copy.

I'm trying to find a solution where I can set and forget backups to the cloud.

My requirements are:

1. It doesn't require me exposing the rest of my file system/cloud storage to a third party app without scoping (filesync works, but doesn't meet this criteria).
2. It can upload directly to a cloud service

So far, no dice :/

Is there some workaround?

P.S. my potential solution is move Signal to my Shelter Work profile, where I do have filesync installed, but then I won't have contacts access, which is a slight pain (and because I don't want to create contacts in my work profile).
