Hi @Mathieu.I ,
Welcome to the community! At the moment, you can access the logged_in users fields. You can confirm what fields you have access to by adding a custom code block on the page, and typing in “Logged_in_user” - from there the available fields will show in the dropdown for you.
However, it’s limited to that at the moment. We understand the need to expand this, and have it in our plans, but can’t give a date on when it might be released at the moment.
