How do I edit the name of the room?

Edit the Room Settings

Go to Room Settings from the lefthand sidebar.
Edit the fields that you would like to change. You can add your room to a Workspace, change the Room Name, Roomy Type, Closing Date, Transaction Amount, Asset Type, and more.
Once you are satisfied with all the changes that you have made, click Save at the bottom. Then all your changes will be updated throughout the room.
