Hi @Ivo Fernandes

There is no presence app as such that would pick this up.

A few ways you could potentially manage this
1.) Put the app in a private channel and when one person needs to use the app, add them and when one person has finished, remove them. This would kind of work as a form of privileged access management
2.) You could, when people are using it, rename the channel name with an emoji. To do this simply edit the channel name and select windows button + . and then set a red X emoji on the channel name when in use, and then set a green tick when it is available

They are not automated ways of management. Something like this doesn't currently exist. You could do down the route of custom development however this could be expensive. If you want to see a feature like this in Teams then it would be recommended to open a user voice for it here

Hope that answers your question

Best, Chris
