How to open three.js on iOS Mobile phone?

I published on github and can open it on desktop(chrome).
But I can’t open on mobile phone. I think it can’t load JS files.It opened just html background.
I tried chrome, safari. also, I tried install three.js(not use master files), but I can’t open it.
How can I open my project on mobile?

Import maps are not supported in Safari yet. You need this shim in your HTML page similar to the official examples:

Thank you!
I modified my html to comprise js script with shim and It works.
