Rest API update attribute options

[Miroir Studio]

[EDIT: SOLVED I was looking at an old rest documentation. They now added the PUT endpoint]

Hello, I need to update the option of a "select" attribute in Magento (2.4). I've noticed that there is no PUT endpoint for the attribute options API. So I'm trying to use the PUT endpoint to edit the whole attribute but it's not working since I'me getting the error ("Attribute with the same code already exists"). This doesn't make sense. How could I update an option label?

or use the POST method for adding and updating attributes.
