Use API calls to send query and receive response instead of from end

[rpaGuyai]

I have already successfully provisioned this app within my company's corporate Azure Tenant and documents which serves as RAG, source are some policy documents.

Query - Now I have another chatBot - not hosted on Azure, actually it's openWebUi hosted on our AWS server, is there a way I can make API calls to Azure OpenAI/ Azure Search which would query the policy documents and return response.

Any suggestion would be very helpful.

Thanks
