How is it possible to enable tool calling like file read/write/execute in Strata (Qwen3.8-next-flash) web ui?

I've just installed Strada and Qwen3.8-next-flash on my PC and I was amazed by it.

The problem is, I cant seem to find a way to enable or add tool callings, so it can read/write/execute files on my PC. How do you do that in Strata?

Thank you very much in advance
