Joplin doesn't see cloud drives in the Android Files app

Operating system

Android

Joplin version

3.5.8

What issue do you have?

I would like to switch from using OneNote to Joplin. I have Proton Drive and Filen cloud storage apps and the data can be accessed through the Android Files app. I have a couple apps that when I select backup or sync data they will show Proton Drive and Filen just like it shows in the Files app when choosing a storage location. Joplin only shows just my local f​olders. How is it other apps can see Proton Drive and Filen, yet Joplin does not?
I have provided a screenshot that shows an example of what it looks like when a difderent app I use asks where to sync a file.
