I have setup an matrix synapse and element on my virtual machine (Ubuntu 22.04).
All is woking fine.
But I need to do some customization in it like as follows. but I didn’t get it anywhere.

  1. I need to change the space name.
  2. I need to see list of contacts directory instead of searching

Can you Please suggest or guide us how can we do that.
