Share an attribute or method between components

I am trying to share a method between multiple components and this method should access an attribute from the parent component. I am using VUE3, with script setup. I tried with “extend” but I couldn’t find how to extend a component with script setup. I don’t want to pass any parameter because in my real case I have many of them, too many. Thank you very much for the support

//TheComponent.vue
<template>
    <div></div>
</template>
<script>
    import common from './Common.js';
    const x=7;
    common.print();
</script>

//Common.js
const common={
    print: function() {
        alert(x);
    }
  }
};
export default common;
