App-Maker How to Assign Roles to Users With Script (NO APP SETTINGS)?

Question

I am learning a bit about​ ​App Maker, and I have seen the​ ​Application Settings -> Security, which can be registered and assigned Roles to users.

How to do this with script when registering a new user in my app?

App Maker doesn't provide a way add/remove roles or add/remove users(group) to/from role in runtime. Out of the box you can manage user permissions in deployment settings (design time): https://developers.google.com/appmaker/security/secure-your-app#secure_deployments

However, you can associate App Maker Roles with User Groups and add remove members using Admin SDK advanced service:

https://developers.google.com/apps-script/advanced/admin-sdk-directory#add_group_member

// Server script
function addGroupMember_() {
  var userEmail = 'liz@example.com';
  var groupEmail = 'bookclub@example.com';
  var member = {
    email: userEmail,
    role: 'MEMBER'
  };
  member = AdminDirectory.Members.insert(member, groupEmail);
}

Be aware, that to run this code you'll need to run your app on developer's behalf (what has its pros and cons...).
