Kmcng V7 and studio

I have been testing the latest repo versions (19.x) and KMCNG V7 (7.10.x) and installed them with success.
However, I haven’t been able to activate the new studioV7 which makes part now of the KMCng. Although I check the studio box on the partners config, it simply doesn’t show on the KMCng.

I believe I need to activate some conf somewhere but haven’t been able to find out where.

As usual, any help will be greatly appreciated.

Thank in advance,
