Hi
As Vasil Michev said, you can create a private channel in a Team and invite specific people in the team to the private channel, which is similar to creating a small team in a large team.
Private channels in Microsoft Teams create focused spaces for collaboration within your teams. Only the users on the team who are owners or members of the private channel can access the channel. Anyone, including guests, can be added as a member of a private channel as long as they are already members of the team.
For example, a private channel is useful in these scenarios:
- A group of people in a team want a focused space to collaborate without having to create a separate team.
- A subset of people in a team wants a private channel to discuss sensitive information, such as budgets, resourcing, strategic positioning, and so on.
