Every journey map starts with a persona. There are 2 ways you can add a persona to a journey map.
1. Create a persona beforehand
The first option is to create a persona beforehand and then select it inside the customer journey map editor. Just click on the persona Add Persona button on the left panel and you'll see a popup window with all personas that live inside the project you're currently working with.
You can add multiple personas to the same map.
2. Create persona inside the map editor
You can also create a persona from the inside of the CJM editor. Just open the ADD PERSONA popup, upload an image, and a new persona will be created automatically.
You can edit it in the Personas Tool any time by clicking the blue button EDIT IN PERSONAS.
Note: To use personas' photo generator, you need to create a persona in the Personas Tool, not in the CJM editor.
