Iframe api sendEndpointTextMessage with octo videobridge

Hello

I set jitsi meet to octo.

jvm 1 server, videobridge 2 server (region1, region2)

It works fine.

If 3 people join the room

A = region1

B = region1

C = region2

There was a problem using sendEndpointTextMessage on iframe api.

If A sends it to B, it’s normal reception at endpointTextMessageReceived.

If A sends it to C, it cannot be checked in endpointTextMessageReceived.

How can I set it up to get it from other videobridge?

Where should I look?

thanks
