I have a dashboard linked to an esphome instance running on another machine. This URL is running via nginx reverse proxy to add TLS support. When I go directly to the https URL I can compile and upload esphome images to the desired serial port or OTA. When I use this same URL through a sidebar dashboard in HA I get the error below. Are there setting somewhere I need to change to enable this?
An embedded page at <my-external-esphome-url> says
Unable to connect: Failed to execute 'requestPort' on 'Serial': Access to the feature "serial" is disallowed by permissions policy.
