I have created a WOrdpress Website with Ultimate member and Metabox installed as plugin, both free version.
I wan't that the users logged in with Ultimate member can create modify and delete one custom post type "Artiste" and only one. I have created a custom tab in  the profile in the Ultimate Member, and I want that these fields to be displayed in this tab. 

I'm an experienced developper. I have already created a custom post type Artise with a metabox for the Artiste but it is displayed in the backoffice of Wordpress, I want the user to create modify or delete it in the frontend.

What dou you need as information to provide me the code to make that happen ?
