How to edit Yandex Disk files on mobile?

Question

Android

Here , Yandex's help says that "there is no synchronization in the Yandex.Disk mobile application."

However, on Android, via Cryptomator (connecting to Drive via WebDav), I can edit files and save, which is convenient. There is an Autosync application , a lifetime license for Yandex Disk 600 rubles, for all major cloud + webdav + FTP, the price is 260 rubles / month. Is it possible to edit texts on Yandex Disk through WebDav for free? Is someone doing this? If yes, how exactly?

UPD I'm still testing the free application FolderSync , I had to tinker a little with setting the synchronization parameters. If the flight is normal, I will stop on it. Write about alternatives anyway, if they exist, maybe someone else will come in handy.
