Have a way to see agenda items without starting a call

The agenda feature is super powerful. I use it in many Talk rooms. What I miss is a way to look at the collected agenda items without having to start a call.

Use cases:

1. I'm the owner of the meeting and want to check before the meeting starts what people put on the agenda to have the chance to prepare some topics
2. I'm not sure if a topic is already on the agenda or not. Having a quick and easy way to check would be great

Possible solutions i have spontaneously in mind:

1. have tab on the right sidebar "agenda for next meeting". Would be a nice and intuitive way to find the agenda points for the next meeting. It would also allow for future improvements like (remove agenda items again, edit them, add new items in a graphical way). It would make the feature way more visible and advertise it, imho something the feature definitely deserves.
2. Probably the easy solution: introduce another command, e.g. "/show-agenda" which shows the agenda only to the user who executes the command directly in the chat.

No file or test is named. Start by tracing the existing agenda feature and its chat-command handling, then compare the proposed sidebar and /show-agenda approaches. Done means users can inspect collected agenda items without starting a call, with the chosen interaction documented and covered by suitable tests.
