Background music to all scenes

hello everyone, i started playing with appinventor for a few days but i have a problem, i can't figure out how to put background music, which continues in all the scenes, without interruptions.
Can someone explain the procedure to me please?


Place the music player on screen 1 and do not close it by opening other screens.
Test in the compiled apk, because Companion may falsify the behavior of changing screens.

Ok... now i have this command

How do I tell it not to close when scene changes?


Btw, it is also possible to stop the sound on Screen1 from Screen2 or Screen3.
