Cerulean ROV Locator on Qground control

Goodmorning everyone,
I write here hoping to find help for integrating the CERULEAN ROV locator system into Q-Ground control.
Cerulean has released a Companion APP which, they say, should allow their underwater positioning system to be recognized and managed by QGROUND.
Surely it is I who do not have sufficient computer knowledge, but I cannot in any way make the program work.
I work with the latest stable version of QGround x Winows 10 64bit (4.2.0).

All the setting parameters reported by Cerulean on the following page:

they are no longer present in the program or are ‘hidden’ in some setting page that I cannot identify correctly.
Is there anyone who has already done this integration and can help me with a step-by-step procedure?
