Hello everyone !
I think i will need assistance from MS team on this one...
I am generating a package from my dev tenant.
What i have done :
I have generated a package for my app, and imported it on my new tenant.
The only big problem i have is this one :

For my last data connexion, I try to select during import, and i don't have any pre-selection or just the ability to choose my authentification for this data connection (O365 Outlook COnnexion)
At first I thought it had to do with my O365Users connexion, so I deleted that data connexion (rebuild it after, no worries)
but it could be the one used under flow to send an email with Outlook.
But, anyway, how am i suppose to finish my import if i can't even connect to my last data connection ? Do you have any idea? Do I have to o a complete rebuild of my app ?
Thanks a lot.
Have a nice day.
