Failure to set-conditinal breakpoints and debug-focus with vscode-nsight

Hi. I am working with vscode 1.68 + nsight-vscode v2022.1 + C/C++ extension 1.10.7.
It is possible for me to set breakpoints in cuda kernel and see vars. The things I find no to work are:
(a) I can’t see the blockIdx and threadIdx content .
(b) conditional breakpoints seem not to work.
(c) the debug-focus is not displayed and when I try to set it through command-palette I get a message the debugger must be stoped before this could be done. not understood.
(d) registers portion in VARIABLES window presents only cpu registers , not gpu’s.

any help with the above will be appreciated.
thanks.
