How do you access the css of the button once encapsulated by the filedownloadwrapper? From what I read on the internet, it seems that we must do so but I have no result.
<dom-module id="my-file-download" theme-for="file-download-wrapper">
<template>
<style>
:host {
--my-color:rgb(0,0,0,0.4);
}
</style>
</template>
</dom-module>
<dom-module id="button-link" theme-for="vaadin-button">
<template>
<style>
:host(.my-class-button){
color:var(--my-color, rgb(0,0,0,0.4));
}
</style>
</template>
</dom-module>
