Yes, but she's severely underutilized.

Originally she was supposed to appear in the Black Widow post-credits, but we got her a little early during Falcon & The Winter Soldier.

She also had a brief storyline in Wakanda Forever, but that hasn't really gone anywhere.

The Black Widow setup gave us a Hawkeye storyline that didn't really make sense, but it did get Yelana into the main story.

The Falcon & The Winter Soldier story gave us Thunderbolts.

Thunder is finally when she's really doing things, but that film needed a little more breathing room.

I expect she'll be wayyyy out of her element during Doomsday/Secret Wars. (Plus no need to be secretive when the world is falling apart.)

I hope she gets a chance to really shine in the future.
