Could iOS app provide nginx a client certificate?

It’s pretty easy to configure nginx to only allow connections from browsers with a locally-created client certificate, which can be a useful way to limit access to the Jitsi conference server to authorized users. It’s also easy to install a user cert in a browser, where I can confirm it works as expected. It’s also easy to install the cert on an iOS device, but the Jitsy Meet app doesn’t seem to recognize or respond properly to the cert request when it connects to nignx.

I think this would be a very valuable feature.
