BuddyPress.org

Hello,
I’m using a plugin to create forms and registration forms on my WordPress website.
It’s WP Fluent Form Pro.
I want to fill the extended profile fields of buddypress from the registration forms I create with the plugin.
The support of the plugin says that I can use the user meta for passing other inputs to BuddyPress fields. They don’t want to help me more claiming that I have to find the solution by myself…

My issue is that I don’t find any User Meta in the extend profiles of buddypress. Where can I find them?

Thank you for your help.
