CMS-API 3.0 /calls/<call id>/participants/* with filterIds=<participant id> and mode=exclude

[Thomas GER]

Hello,
i tried to use the endpoint

/calls/<call id>/participants/* 

to mute audio for all participants, excluding one specific ID:

rxAudioMute=true
filterIds=<participant id> 
mode=exclude

But that does always change ALL participants.

The "filterIds" attribute is always ignored.
(Also tested with the Postman-Samples and double checked the CMS-API logs -> My API-Reqests are apparently correct.)

What did I miss? Thank you in advance!

The solution is:
We must send "filterIds" and "mode"  as a QueryParams, not in the Request-Body!

(I think the API-Documentation could be improved:
