Profile completeness

Hi all,

I’m working on a website in which we use profile completeness widget from ultimate member. What I do is save custom user meta to the user when he saves his profile. These are custom field in his profile, but I did not create these fields with ultimate member.

Now I want to use these custom fields with profile completeness. I can’t seem to find out how to do this. I know I can’t choose these fields once I want to add new fields to completeness, but surely there must be a way to add these meta fields by way of coding using a hook or something.

Does anyone know how to do this?
