Creating a loading bar

Hey I'm super new to animation software (beyond Photoshop gifs) so was wondering if Animate is the best to create a looping loading bar or I should just bite the bullet and jump into AfterEffects?

If Animate can do that, and there's a tutorial - doesn't have to be exact - that I couldnt be pointed in the direction of that'd be much appreciated.

Not sure if it's relevant but I'm very well versed in Photoshop, Illustator, and InDesign.

Thanks!
