Can I add the Agenda app to MS Teams?

A range of apps can be used within MS Teams. Is it possible to use the Agenda app?

Not sure what “can be used within MS Teams” means? Can you give some examples of what other apps allow you to do?

Apologies for not being clear. In Teams there are channels. At the top of a channel there is a plus sign to add apps to each channel. I would like to add Agenda for my team to work with but it is not coming up as an option. I have taken a screenshot so hope it shows what I mean.
