Vanila Javascript Es6 Modules not working on Safari browser on Windows

I have a small code which works fine on Chrome, Opera, Edge and Firefox. But it's not working on Safari.

I am a windows user so I not that familiar with Safari in order to find out what is wrong.

I was using this website as reference but I am not sure if it's updated or if maybe i could have misunderstood something. But I guess it suppose to work.

https://caniuse.com/?search=javascript%20modules

I am using apache and php

I have 3 files (index.php > index.js > Entities/Contato.js)

Tried to let it as simple as possible but let me know if you need anything else.

Thanks

index.php

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>

</head>
<body>

<!-- This one works just fine -->
<script>
    console.log('init'); 
</script>

<!-- This one does not work -->
<script type="module" src="./js/index.js"></script>

</body>
</html>

index.js

import {
ContatoEntity,
} from './Entities/Contato.js';

$(document).ready(()=>{   
Main.ContatoCreate();
})


class Main {    
static ContatoCreate(){
        let contatoCreate = new ContatoEntity();
        console.log(contatoCreate.getContatoId());
    }
}

Contato.js

class ContatoEntity{
    constructor(form) {
        this.form = form;
    }
    #contatoId='123';
    #contatoNome;
    #telefones = [];
    getContatoId(){
        return this.#contatoId;
    }
}
export {
    ContatoEntity,
}

Solution

thanks again. I was trying different approaches and when I change the code I found a first error and when I searched for this error I found this 2 links which could kind of explain what is happenning. The thing is Safari Windows had its last release in 2010 Safari: SyntaxError: Use of reserved word 'class'

(portuguese - but not but explanation about versinos and stuff) https://support.apple.com/pt-br/102665

Thanks again Gonna change it to solved now
