STOP an animation from looping in Adobe Animate?

[DEBBIE5E3B]

Hi! I hope there is someone who really knows how to help me.
I have an animation that right now is six seconds long. When I test it , it repeats even tho' I have it set up NOT to loop and the Movie Clip Symbol is not set up to loop.
I have the Movie Clip in the main timeline (scene) after I created it.
I even added a stop action as I saw somewhere else to do this, but it doesn't work.

Please, can someone help me? I'm using Animate 2024.
I used Animate a few years ago and never had this issue!

Oh, and I have Looping UNCHECKED in the Publish settings.

Movie Clips are only for interactive projects.

If your project is not interactive, use Graphic symbols, not Movie Clips. Graphics can be set to Loop, Single Frame and Play Once.

You can switch the instance type in the timeline to Graphic, but you need to do this in every single keyframe.
