I want to see my server member list without fully swiping the right sidebar

The new UI is not that bad, but it was indeed weird because it does not match Google stock android theme. But my main complaint on the new UI is that I cannot view my server participant list by slightly peeking the participant sidebar. In a private server where there's just barely 10 members joined, this is something I frequently do on mobile, trying to see who's online at a glance.
