How can I create my own user roles?

Is it possible to create own user roles? For example I want to create a role like App Viewer, but without the possibility to invite other users.

Hey, unfortunately, restricting App Viewers from inviting other users is not possible. But we are working on this feature. You can track it here - [Feature] Ability to give viewer access to an organization, without letting them invite others · Issue #4494 · appsmithorg/appsmith · GitHub

We’re also working on enabling granular access control for different user groups - [Epic] Granular Access Control · Issue #3317 · appsmithorg/appsmith · GitHub
