How to loop Scene 1 to prevent it to proceed to Scene 2 automaticially?

Greetings dear helpful peoples,

as you see i am new to Adobe Animate.

I learned how to create a scene, also scene 2, scene 3.

How to implement buttons and use them for switching between the scenes, i love this!!

But now i am stuck, my problem right now is, when i play the whole thing, it goes at the end from scene 1 directly over to scene 2.

Some peoples said "make a movie clip" so i learned this too, i turned my PNG into a movie clip then animated it again and now it shows the animation inside thr movie clip thingy. The problem here, it diddn't change anything. So it was nonsense, but at least i learned something.

My question is:
How i can loop scene 1, the entire scene and prevent it from switching to scene 2?
I made a button to switch so i want scene 1 to loop, until i press the "Next Scene" button.

Regards,

Samantha.
