So I may be misunderstanding the question, but I am not aware of any hybrid integrations for Adobe Target. There is the native library, as you already linked, and there is the client side which you refer to via DTM. The documentation on how to call Target is here:
at.js functions overview
Perhaps you are asking how to get native and web to talk to each other and that could be accomplished via query string params into the webview that opens up the client side app. You can pass through the tntid, session id, etc. in order to have it around in the pseudo web browser.
Maybe a bit more information would help me better understand the question.
