Warning in a custom button

[msakal20]

Hello, I have a problem with custom button, when I create a new appearance, I have this warning, from it, I can see that the component button takes only 3 values ["default", "minimum", "main"], but appearance work.

The same warning I see in documentation.

Сan I fix this warning ?

Good spot out! Honestly, we can loosen up the prop types / typescript types to accept string that'll help get rid of these errors (while still maintaining typesafety). Happy to accept PRs!
