Microsoft Teams Export

[lmstearn]

Anyone use MS Teams (free, gui version)?
Gone down the rabbit hole of an issue involving MS Teams (free) channel content, switching to other MS accounts (if you have them) in their gui interface is not available.
Unfortunately, have to wait 30 days for the fruit of the solution to that question to ripen (edit: no need), so what are the alternatives?

A quick Google comes up with something that looks like a goodie, MS offering an API to export content. Going down a little further, a request form is to be filled. This is done via MS Graph:Channel:GetAllMessages, for that to be used, unfortunately no permissions allowable for delegated users.
For this purpose, it may be more convenient to go to another language when considering a decision to sign up to Azure, where the pay as you go idea is certainly an improvement to what it used to cost.
Doesn't look as if AHK can do much with it, maybe a way of using Net Interop to interrogate the MS.Identity.Namespace in MSAL. Who knows?
