Need help to implement html/js in kodular app

Can anyone guide me how to implement

Video to Lottie / Forrest Oliphant / Observable

This website’s video to Lottie json conversation features in app

Just download Json file or copy url then drag Lottie Component and used it.

I know that thanks for your concern buy I want to implement that feature in a app made by kodular

Do you wants to create an app which can convert a video into Json file.

Yes I want to do that and want to learn how to do that

Maybe not possible, if this website provides api features then maybe possible, search it.

It uses JavaScript to do that work I just don’t know how to implement in kodular app
