How to install custom Kibana plugin 7.9.2 from local directory inside Docker container?

Good day, in order to troubleshoot our plugin we wanted to test it via a docker container.

So at the moment I have managed to download a plugin zip from our repository to the Kibana docker container but I cannot figure out the location path for installing it:

Following the command structure from the documentation hasn't helped much: e.g.

bin/kibana-plugin install file:///local/path/to/custom_plugin.zip

The zip file is located in the bin directory of the Kibana docker container right alongside the install command.

I figured it out via some reverse engineering, posting answer for others:

kibana-plugin install file://{container-id}:/usr/share/kibana/bin/postmanPatPlugin-7.9.2.zip

Thanks for posting it.
