I am looking for a channel pin(fixed) function

I am looking for a channel pin(fixed) function
When I bring up the channel list, pinned channel should always be on top.
I have tried channel inside custom type “PINNED”
ex)
let channelListQuery = sb.GroupChannel.createMyGroupChannelListQuery();
channelListQuery.customTypesFilter = [“PINNED”];

I thought I solved… But it wasn’t the way I wanted
I want to save it in the same way as this
ex)
pinnedUser: [“userId1”, “userId2”]

I want to put in data and filter by data
ex)
channel: {
data: {
pinnedUser: [“userId1”, “userId2”]
}
}

when userId1 bring up the channel list, If you look up a pinnedUser in the data and include “userId1”
fiexd top. Please tell me the solution
