Help need for Build Support Bot

Hi there, I was trying to build a bot that can help users get a better experience. Like they can easily get a tutorial on Nextcloud without the help of another.

Please help me. I have created a chatbot and given it a public IP. and I tried to integrate with Nextcloud using an external site option.

But I want to build an entire chatbot that rules the Nextcloud at a fingertip. can anyone help me, please?
