I have been using flows to add new users.
Our exchange is in Azure, so have connected flow to a form for Admin, so that as a new user joins it auto creates school 365 account, email and licensing. Am just awaiting for MS to create the ability to add new users to groups via flow.
(Have also played with 'Alexa' and can see how to do this using Alexa telling her to add new User - this is more fun than functional, her spelling can be atrocious)
We are currently looking at an HR Flow.
Have you played with Power Apps?
Being an SEN school, teachers and ta's use a lot of temp items such as buttons, iPads, microphones, headphones etc etc, having a power app to keep track of this stuff, and to allow users to login into to see what they currently have against there name is a useful resource.
