Fused New User Failed Unless from WordPress Admin

Tried this plugin by creating new user from wp-admin and works flawlessly. It managed to synchronize with my mautic based on the rules I setup.

New user in wordpress with no user in mautic.. It creates new user in mautic.
New user in wordpress with existing user in mautic.. It updates the field in mautic.

Perfect!

Now I tried creating new user NOT from wp-admin but from a third party plugins (such as membership plugins) to create the new user in wordpress.

The user is created in wordpress, however I can’t see any changes in mautic. The plugins probably check a new user created only from wp-admin. Is there any solution to fix this issue? Thanks
