Is it possible to use client cetficate in Boundary desktop?

Hello.
I use the Boundary cluster under Nginx. Nginx uses SSL client verification. I use Windows, and I put my p12 key in the Personal folder in the certificate store. Concecting via a browser works, but on the Boundary desktop, I get the following error:

Unable to connect to the specified cluster URL. Please check the URL and try again.

I also tried to use the client-cert:

"C:\Program Files\Boundary\Boundary.exe --client-cert C:\Users\alekesej\Documents\secrets\loc-client.pem"

I’ve tried using p12 and simple pem formats. And also, I don’t have any logs in nginx when I try to connect to the cluster using the Boundary Desktop. But using a browser, I see log lines in access.log.
