In the video below, it is explained how to create an automation (starting from 5:43).
Please note: In general, we strongly advise against making changes to an active automation. This can lead to unexpected errors. Therefore, always set the automation to 'Inactive' before making any adjustments!
If it is a situation where it is necessary for the automation to be 'Active' (e.g. starting contacts in a specific location), it is better to set this aside.
