How to make the button "Share to Instagram Story in Tik Tok?"

Hello, i would like to know if anyone knows how the Tik Tok button to works to share a video from this plataform in Instagram stories, that is, the button opens editing mode with the video already included. I would be needing to make a similar button for an application. i tried entering URLs from my phone like: "//instagram.com/create/story" but it doesn´t even open the story editing mode. Thank you very much.
