BQ25773: I don't see BQ25773 is in the supported hardware list of BQstudio

Tool/software:

Hi team, 

BQ25773 is not in the supported hardware list of BQstudio (stable or beta version). BQSTUDIO Application software & framework | TI.com

I downloaded the bqz file from BQ25773: Where is BQ25773_773G.bqz file? - Power management forum - Power management - TI E2E support forums and copy to BQstudio config folder. 

However, when I try to read register with EV2400 + BQstudio, I always get Device ACK error. The same setup works fine on another product with BQ25723. 

I am wondering if I need any specifical version of BQstudio that supports BQ25773, or if there is any secure protection in BQ25773 IC that stops BQstudio to read the registers. 

Thanks

LL
