how to make the Live agent handoff work for other channels

So I developed the live agent chat handoff to my chatbot so theres that additional feature that ive coded through the demo react app and i want to integrate this live chat handoff feature to other channels like messenger or instagram dm which was possible (when making the chatbot with voiceflow only) using the dialog management api but now since the additional feature of the livechat handoff is coded through the demo react app and that feature isnt available through the dialog mangement api is there a possible way to connect my demo react chat to the dialog management api or do i have to make my own apis just so i can integrate to the other channels

if the explanation above is too confusing basically: how to integrate the live chat handoff that i have setup in my demo react chat to other channels like instagram dm , messenger , whatsapp?
