Is there a way to change the output of the Web Storyline with Flash in such a way that it works with new browsers that do not support Flash?

Hello and thank you. So all the projects that our friends have worked on and have taken the web output with flash cannot be used directly, and you can only use their resources and rebuild the projects, and this will take a lot of time. Flash project can no longer be used!I used multimedia builder software a few years ago and publish as .exe.with a press button i can decompile that.i used password for security.
