What name is given to the challenge started by the mysterious tower in Pokémon Pokopia?

The mysterious tower starts the Team Initiation Challenge in Pokémon Pokopia.

During the story, Ditto and Professor Tangrowth discover a mysterious tower. Its machinery initiates the Team Initiation Challenge, which requires Ditto to provide certain items supposedly intended for Pokémon welfare.

The challenge is part of Pokopia's larger mystery about the disappearance of humanity and the damaged condition of the world. At first, the tower's requests appear to be connected to Pokémon wellbeing. Later events reveal that the structure has a much larger purpose than a simple test or construction project.

The name can be confused with the game's general habitat-restoration objectives. Those activities are central to normal progression, but the Team Initiation Challenge is the specific named sequence activated by the tower. Completing it, alongside restoring habitats, leads to the story's dramatic rocket-ship revelation.
