Is there a way to hide the channel list sidebar on the left side when in stream mode?

Currently watching a stream on a Discord server as I write this message. On the left half of my screen is this browser where I’m writing this message. On the right is Discord and from left to right, I see (1) my server list icons, (2) channel list, (3) a friend's stream of a game with a list of participants at the bottom.

Since Discord is only in the right half of my screen and I’m only interested in the stream, I am finding it unnecessary for the channel list (item 2, sidebar on the left) is visible all the time. Is it possible to hide that?

I also noticed that I can hide the audio participants from the list on the right, but when watching my friend's stream there is still a column on the left that shows the list of participants, one of which is said friend's screen/stream and can't be hidden since I'm watching it. This list feels unnecessary when using this setup though and makes the stream smaller, is there a way to hide that as well? Or maybe to re-arrange items so that the list of participants / additional video streams are above or below the stream? (I think Zoom has that option)

I would attach screenshots but it seems like that's not an option here; I would be happy to describe this problem further or send screenshots some other way.
