ADM app for Android can't open .acsm

I purchased an ebook and downloaded it in the .acsm fomat. I downloaded the ADM app for Android, but it doesn't open .acsm. I've looked through all possible settings to switch the file default on Android 9, but I couldn't change anything regarding default app to open ,acsm... I have this same book on my ADM on windows... is there a way to sync the library? Please help.
