Which database table holds user roles

Hi all,

we created several user roles on ultimate member. There are 2 columns there, Role Title and Role ID.
I was able to find the Role ID on the wp_usermeta table. There we have the umeta_id, user_id, meta_key and meta_value. The meta_key capabilities have the meta_value “a:1:{s:6:”vendor”;b:1;}” where vendor is the Role ID. But there is no meta_value with the Role Title.

My boss wants a simple dashboard with the number of users per role, but I would like to show the role title and not the role id.

Does anybody know which table has the role title?

Thank you.
