How can I spotlight user in CustomUI mode?

I use windows sdk version 5.4.54802.0124 with customUI as host, and have more than three other participants who use standard zoom style user interface with kinds of devices.
Now I try to spotlight user (GetMeetingVideoController()->SpotlightVideo), it does not work.
All these three fuctions: SpotlightVideo, UnSpotlightVideo, and UnSpotlightAllVideos return error code 3 (SDKERR_INVALID_PARAMETER,///<Wrong parameter.)
Actually the parameter is correct and even UnSpotlightAllVideos does not require parameter.

Then I noticed the comments said “Valid only for Zoom style user interface mode”, so does this means these three functions not work for customUI? What’s your purpose these not be supported in CustomUI mode? How can I spotlight user in CustomUI mode since I really need such features.

Thank you.

Hey @Rex_Wang,

Thanks for using the dev forum! It is good to see you again.

Yes, spotlights only work in default UI now. I will ask the team about why this is.

Thanks!

Hey @Rex_Wang,

I understand this is not ideal for your use case. Unfortunately we do not have an alternative at the moment.

Thanks!
