Leaving a company removes your access to its brands and data; it does not delete your personal Nonli user. Before leaving, make sure another active administrator can manage users, roles, billing, bots, websites, and social-account authorizations.
Open the main menu, switch to the company concerned, open its membership or company settings, and choose the leave action. Read the confirmation carefully and verify the company name before confirming. If you are the last administrator, assign a replacement first; the interface may block the operation to prevent an unmanaged workspace.

After leaving, sign out and back in and confirm that the company no longer appears in the switcher. If you left the wrong company or still need historical access, an administrator of that company must invite your individual user again.
