Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Microsoft has a very simplistic option with Office 365 called Planner that might suite your needs. It does not have a lot of functionality, but may be what you are after. I know it is included with the enterprise subscriptions, but not sure about the others. Here is the link just in case:

Hope this helps.
