List and Delete MFA's of user

I need to list all MFA’s previously registered and i need to be able to delete them.

So, what is the best way to do it?

I’m trying to use GET /mfa/authenticators, but when I tried to get the list i couldn’t and received following error:
“Could not retrieve an access token with scopes “read:authenticators”. The user will need to sign in again”.

I’m already using scopes on login (as an image bellow)
