On the left of your agenda, you have the other calendars of your organization
If you want to simply select one more calendar, just click on the checkbox.
If you want to select only one (and deselect the others), move your mouse over the First Name and you will see a button “Only”. (It's working for the specialty to select all the Hp in a specific specialty)
