how instantiate game object prefabs in multithread project

Questions & Answers
1

I’m using gRPC whith Dialogflow in Unity, and the core of the project is Streaming data in multithread.
I have a background task who run the response and a foreground task who run the request.
Everything work until i need to instantiate gameobjects (text or audioclip) from each tasks, specially from the background tasks.
i tried to use coroutine for instantiate data in gameobjets after .movenext of task but it did’t work well.
I’m a beginner dev, and i did’t found a clear answer to my problem on the web.
Thanks for everything
