I'm looking at building an app in PowerApps For Teams. I would guess that a huge use case for PowerApps in general is rebuilding on-premise applications, however in PowerApps For Teams at least it seems to be inordinately difficult to get legacy data into an app.
So what's the best approach for doing a one-off import of legacy data (I can present it in any required format) into a PowerApps For Teams Dataverse table?
Thanks
