When participating in zoom meeting with Poly Codec, can't see Poly Codec video on poly side?

jinhyuk,  I'm not entirely sure what you're asking but we have multiple Polycom GS-500 Codecs, some with 2 displays, some with only one.  When in a Zoom meeting, the Polycom Codec should be able to see their own video IF they select that option from the Codec remote control.   The codec controls local view, not Zoom.
