[keycloak-user] Update user account with API

Hi I want to authorize a user to update his Keycloak data from my application thru the Keyclaok api. By defaut my user can’t use the api to update his information. If I set manager-users role to my user he is able to update his information but also the account information of other users. How can my user be able to update only his account ? Best regards Loïc
