I HAVE AN ERROR 'YOU ARE NOT AUTHORIZED TO INSTALL THIS APP, PLEASE CONTACT YOUR DOMAIN ADMIN.'

If you are a Google Workspace(G Suite) user, the app needs to be installed through Google Workspace Marketplace. Your admin can install it and can assign you to access it. If you are a G Suite Super Admin and have installed the app but get this error message, visit admin console,  Security > API Reference and enable API access.
