Could someone post a step-by-step procedure for enabling/install Anbox on Dora device (F8131) and how to install android-Apps (or .apk files)?

I could confirm this problem happens on my Xperia X Performance:
No ringtone when receiving a call.
This problem happens on stable chanel as well on devel for Dora-device. (Both with current releases available at 23 March 2021.)
