play a sound in the background in editor mode

Hello community,

I want to put background noise, or background music in a UE5 project, while leaving it active automatically as soon as the project is opened.

(Exactly like the default Unreal engine scene with the 2 armchairs and the table - see image 1).

I tried with a copy/paste of the audio tool present in this scene, but I have to activate it manually in the tool window (see image 2).

Do you know how to leave it permanently active, as soon as the project opens?
