Filesystem mounted in docker

[JoseDesfilis]

I have the ADDON installed in Home Assistant Supervised. I am trying to configure ssl_client with a self-signed certificate. I need to upload the certificate to the nginx server, but I can’t find where to leave it.
Is there any filesystem in homeassistant that is mount on the nginx server?

ssl_client_certificate /path/personal.crt;
ssl_verify_client optional;
ssl_verify_depth 1;

I solved it with a workaround.
I have added in Edit Proxy Host > Advanced these lines:

ssl_verify_client optional_no_ca;
ssl_verify_depth 1;
if ($ssl_client_fingerprint != “<finger_print>”) { return 403; }

Where <finger_print> has the value of the authorized certificate field.
