Stuck on how to do syncing and backup version with multiple devices

What I’m trying to do

I’m trying to have my vault in a laptop and access it in two other Android devices remotely. From what I understood, bidirectional sync using two different types of services is not recommended as it will cause issues. But I’m not sure if what I have in mind is possible? Can I have syncing across multiple devices using Google Drive and use a git repo with the git plugin to have a “backup version control”? Essentially, the laptop would be the bridge (?) of everything - it would host the original vault folder and make the backup versions and the devices would use some sort of third party app to sync with the Google Drive. My problem is that I really can’t figure out if this is something I can do or not - I got really confused reading stuff here, seeing YT tutorials and reading stuff on Reddit. If I can do it how?

Things I have tried

I tried to follow a tutorial on YT in my native of language someone making this Google Drive+ Git set up and I think I messed up because of language comprehension? I'm not sure. Maybe I did something wrong while setting things up. Still, from what I understood from the video ( from Navegamente) I would need to set up the Google Drive part first and then the Git part. Well, I think I messed up the Google part - because it just shows the files synced to it just freely on it and not inside a folder and that way I can't set up the whole syncing across devices stuff because there isn't a specific folder for my vault. Plus, I complemented the Git part with the video of a English speaking YT (Fleeting notes) as the Navegamente tutorial didn't say anything about the API key part. However, because the Google Drive part didn't actually work I really haven't move futher to do the syncing across devices part because it's apparently impossible without an specific folder.
