Update position and Roll user

Hello

is there a way for the user to update positions, roles, etc. through the web service?

In the update rest api section, it is only possible to change the name, phone and email. I want to be able to change the positions and roles with it. If it is possible, help me how to do it. I have the link https: / /help.bizagi.com/bpm-suite/en/index.html?scim_create.htm, which was for the update, I read in full, but it does not mention a change of position, it is used only for name, email and phone.

please guide me .
