POST /api/v2/users: Connection is disabled

Hi,
I’m writing a python script to facilitate the management of my users but when I POST /api/v2/users, I get the error

{
  "statusCode": 400,
  "error": "Bad Request",
  "message": "connection is disabled (client_id: xxxxxx - connection: email)",
  "errorCode": "auth0_idp_error"
}

According to a similar issue, I wanted to enable the connection in my app setting but I do not have that tab:

This application is a type “machine to machine” an its purpose is for management and I believe I did grant it the required permissions.

On the other hand, my user facing Native application does have that Connection tab.

Where can I allow my management CLI app to access my email connection?

cheers
Jan

Found it. the Application has to be enabled in the Connection settings
