This activity is suitable for getting to know each other, it can be implemented at the very beginning. The students work in groups of two in a breakout rooms. The educator can provide them with a list of questions to ask each other. Each pair of students now interviews each other in e.g. chat..
With smaller groups: When everyone is back in the same virtual room, each student introduces his/her interview partner.
With larger groups: As results, each student posts the introduction (video, audio file, text) of his/her interview partner.
The results can be posted in MS Teams
The results can be gathered in some app for collaborative working, for instance Padlet https://padlet.com/
