All communication via Matrix takes place within rooms. Rooms can be made available publicly or kept private, and they can configured to be encrypted depending on your requirements. From the Element Matrix clients, Element Web App or Element Mobile / Desktop Apps, rooms can be found under the Rooms section. However when speaking directly to one particular person, a Room is marked as a Direct Chat and can be found under the People section instead.
Rooms, if desired, can be prioritised as Low Priority or Favourite, moving them into dedicated sections named as such. Rooms can also be organised into any number of Spaces, allowing you to further manage the rooms you see. In addition, you can customise the notification settings for each room to alert for All messages, only Mentions & keywords or to Mute room.
