Creating more API assistants locally

I have used an app template “openai-assistants-quickstart” from openai on github.

In the template there is only 1 assistant defined in “openai-assistants-quickstart-main\app\api\assistants\route.ts”, however, what should be done to create multiple assistants with different instructions that are deployed when clicking on a specific link (selecting a category from “openai-assistants-quickstart-main\app\page.tsx”) in the application?

I have tried defining different assistantIds in “openai-assistants-quickstart-main\app\assistant-config.ts” etc., but it resolves in errors.

Thanks in advance!
