"Callception"

Basically I don't know if other users have this same problem, probably not, but I thought something curious,so lets get into the point, so among my friends we have a discord server and from time to time I like to watch one of their streams, whether from Valorant for example, So, the problem comes in these games in which listening to the steps is crucial, if we are other friends talking about anything, we would be "bothering" them and it is not a matter of them "tabulating" to mute us during the rounds or for us to leave to another chat because I would like to see the retransmission of these while I talk about other things with other friends, so I don't know if it would be possible to implement a "call within the call" system as if it were a chat thread where at enter this "Callception" to be able to stay in that voice chat watching my friends "retransmission" while I talk about anything with other friends and at the same time not bother those who need that concentration, so summing it all up, it would not be "useful" but Curious to have the ability within a call to have another call where those users of call 1 cannot listen so as not to be disturbed by those people who want to see their broadcast, but at the same time talk with other friends on the call. The maximum being 1 call within another call. I know perfectly well that all this takes work and effort so I simply leave it as an "interesting" suggestion :3
