We have a scenario where we’d like to consider sending a calendar invite to staff who receive a work assignment on a work task, which can be updated when the work assignment time changes (it will, frequently).

Has anyone done this and if so how?

I was thinking of using a combination of event actions which fires On Transfer To Mobile,  which then calls the Microsoft Graph API to send a calendar invite to the assignee’s email address. When the assignment changes though it’ll need to send an update to the calendar appointment. 
I am pretty sure it’s achievable however obviously a bit of setup and was wondering whether anyone had come across anything out of the box that can do this or has just had experience doing something similar?
