Currently workspaces are using a customized implementation. It might be beneficial to push this down to Better-Auth (for security, organizational and maintainability reasons) - see PR https://github.com/better-auth/better-auth/pull/4348

Describe the solution you'd like

Workspaces natively integrate with Better-Auth, creating a more enterprise ready Sim Studio
