Android端浏览器是否支持Notifications Web API？示例无法正常显示通知的问题咨询

我做了一个展示Notifications Web API基础用法的示例，在Windows和Linux系统的Firefox、Chrome浏览器中都能正常运行，通知可以正常弹出。

不过在Android系统的Chrome和Brave浏览器里，这个示例完全没有任何通知显示出来。

我查阅了Web API相关文档，既找不到关于Android端如何使用Notifications API的指引，也没有看到官方明确说明这个API在Android上不支持的内容。所以想请教大家：Android系统到底支持Web API的Notifications功能吗？

以下是我的示例代码：

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

            }
