No response when joined the videoroom

this.videoRoomPluginHandle.send({
message: {
request: ‘join’,
ptype: ‘publisher’,
room: Number(roomId ? roomId : this.roomId),
},
success: (response: any) => {
console.log(‘Room Joined SuccessFully’, response);
},
error: (error: any) => {
console.log(‘Error Joing Room’, error);
},
});

You may want to better study both the Janus API and the VideoRoom API:

i did read and i got most of i could understand,
i created a room and when i joined it by sending to the pluginhandle for video room i created, with body message:{request:‘join’,ptype:‘publisher’, room:roomId},
the response is sent as a success but am i not supposed to get a response as said in documentaion of video room api like:
{
“videoroom” : “joined”,
“room” : ,
“description” : <description of the room, if available>,
“id” : ,

}

That will arrive as an event, not a response.
