LOGGED_IN data not accessible on Detail list from another data source

Hello,

I am using the dynamic pages to create a Detail page from a List (source: Airtable). The Detail page is opened through a link, that have the record_id in params:

https://myapp.preview.softr.app/workflow-details?recordId=receYuQ5g2q2hZGIp&show-toolbar=true

But, when I want to add some nice customise content for the users, using for example: “Welcome back, {LOGGED_IN_USER:NAME}!” or display any other User record, I have the messages: “Record details can no longer be found.” (screenshot below).

My question: how can I request the user data in a detail page, generated from a list ?

Thanks a lot!
