crs setting for WMSFacade provider

[Bruve27]

Hello,

I am looking to configure a pygeapi server with a "WMSFacade" provider to retrieve maps in various CRS.
For example http://localhost:5000/collections/test/map?f=png&bbox=4,50,5,51&?crs=[EPSG:3812]
Unfortunately, the "crs" parameter does not seem to be taken into account, as the underlying request to the WMS server contains always "crs=EPSG%3A4326".
Is this parameter supported, and if so, could you provide an example of the configuration?

Thank you in advance.
