How to publish to website in version 4.24 and 4.25

I just finished a project I have been working on and now would like to be able to upload and embed it into a website so that other people can navigate through it without having to download the .app file (which is about 1GB). It is an art gallery that I want people to be able to walk through on their browser. I saw a YT video with a process showing how to add the ability to package for html5 to version 4.24, but it doesn’t work for 4.25 and I need the ability to do this in both versions. I also downloaded version 4.23 and tried to migrate my file to a new project in 4.23 (since that version has the capability to publish for html5) but it said my map would load because it was made in a newer version. I am very new to this so I would appreciate any help. I am using version 4.24 and my coworker is using version 4.25. It would be great if there is a way to make this happen in both versions.
