It depends how they hung them. Maybe see if you can ID that exact corbel and find the hanging instructions on youtube then you can reverse engineer it to remove. Have you tried pushing straight up? Sometimes they are on a screw mount where there is a channel on the back that slides over the screw and down. Hopefully, they didn't glue it.

My experience with plaster or wood corbel deco is as described above, here is a picture of a random backside illustrating that:

I tried to push it. It didn’t budge. I’m guessing they glued it. 🤦🏼‍♀️

Thank you! The cornel won’t budge, so I’m guessing they glued it as well. 🤦🏼‍♀️. I’ll google how to remove deco that has been glued and see if there’s any advice.

Can't tell, but the wall could have been painted after it was hung, or caulked because of the wall texture. So you might need to cut that connection around the perimeter.

Drive a stiff scraper around the perimeter first please. Hold a short 2x4 under the curlyques and drive it upward with a small sledge hammer and see what happens.
