Discord Calls : Save the Calls / Time Length of Call (Suggestion)

When you start a call on discord there is like Anonymous started a call. - Join the call.  I think that there should be a feature where you can go back and listen to the call, such as a button next to where it said Anonymous started a call. - Join the call. Go back and listen to call.  Of course this button would show up once the call was over. Something else that could be added would be like when the call ends there should be how long the call had lasted, either how long you had stayed in the call or when everyone had left the call.

This is a suggestion 

Thank You
