Codebook type2 for MU-MIMO

Hello Experts.

Question about MU-MIMO: I keep looking to see codebookType type2 for MU-MIMO.
But I cannot get it.
See picture below:

It is kind of strange that I do not see it in UE logs even if MU-MIMO is activated per cell.
This is at 5G SCG setup.
Actually is important to understand how often users are paired/unpaired fro MU-MIMO per cell since this is a periodic activity
