Can I use a sqlite database on app-platform

Hi, I have a simple python flask app that is creating and writing to a sqlite database (this creates a mydb.db file in the filesystem). I know if I would use “droplet” this would not be a problem but I was wondering if I could also use “app-platform”…I think I don’t because it will run in a docker container that will not persist filesystem changes right ? I tested it with a simple app and it worked (theres no error that I cant write to the filesystem or something like that) so now I’m wondering am I correct that I should not use sqlite with app-platform, and if so, in what situation would the containers restart/wipe the filesystem could it happen “any time” or only when performing some administrative work like changing the scaling plan ?

Also if I cant use sqlite can you point me to resources how to integrate digitaloceans hosted db

Thanks in advance, I’m new to web dev and digitalocean seams really nice.
