access custom fields of the user in course content editor - placeholder?

I would like to show a specific info that is stored in a custom field, accessible via fluentCRM, in the content of fluentcommunity. Or put it into links below a video so that I individualize the users experience.

Is there a placeholder that I can use to access these I formation from the contact fields from FluentCRM?

F.e. {{contact.first_name}} - I know it's not a custom field but something similar?
