{{$env.XXXX}} variables not supported in Autocomplete API dropdown URL

Summary

I'm examining a ways how to connect two our systems with Directus. One of the feature which looks very useful is Autocomplete input (API) element.

Unfortunately it seems that {{$env.VARIABLE}} evaluation is not supported in Interface->URL settings.

Is there any way how to do that?

Same variables are working for me in Flows without any issues (I have FLOWS_ENV_ALLOW_LIST configured)

Basic Example

{{$env.VARIABLE} for URL settings

Motivation

To share same secrets via docker-compose without necessity to paste secrets directly to the URL

Detailed Design

evaluate {{$env.VARIABLE} in Autocomplete API same like it's evaluated in Flow REST API Headers for example

Requirements List

Must Have:

• `{{$env.VARIABLE} evaluation
