Click the gear icon at the top of the left sidebar to open the settings menu.
The dropdown at the top of the menu shows your current organization. Click it and pick another organization, or type to search the list.
Trace.Space reloads with the selected organization.
The same dropdown sits at the top of the left sidebar on the Organization settings pages. Clicking a notification that belongs to another organization switches you there automatically.
