Use integration configuration option (parameter) in template

I’d like to pull a value out of a config entry of an integration for display in the front-end.

In particular, the integration is the FlightRadar24 integration, and I’d like to display the configured value of Radius in meters in my front-end (I’ll worry about converting it to kilometers later).

How can I access this value in a Jinja template?

At the moment, I just hard-code the value in the display, but I’d rather get it from this setting so that if it changes, the display changes.

I can get the config entry title, but I’m not sure how to get the parameters:

{{ config_entry_attr(config_entry_id('sensor.flightradar24_current_in_area'), 'title') }}
