Emnet: Managerless national team

The manager of the Australian U17 team hasn't logged in for three weeks and just lost his team, however, he is still listed as the U17 manager. Is there a process for replacing the manager in these circumstances?

I am the assistant. Can I just be promoted to the manager's position? Or is there a trigger for a new election? Or is there someone who is able to go into the team on our behalf and add players to the squad so I can at least select a lineup?

As assistant, I can select lineups and tactics. Unfortunately, there are only ten players left in the squad so any lineup I attempt to select is disregarded in favour of an autoselected lineup that picks players out of position.

Any thoughts? Surely, we've run into this problem before. Or has it not previously coincided with the change of season?
