I'm trying to programmatically control the relative local volume of users' voices in a Discord channel from a web app.
Discord's Game SDK has a documented API call to control a user's local volume with VoiceManager.setLocalVolume(userId, level) from a native game, but Game SDK approvals are currently on-hold and I'm not trying to make a native game.
So, I turned to Discord browser plugins. On discordapp.com, I can see that a function called setLocalVolume is defined, but I don't know how to call it. The Discord API seems to be obfuscated by Webpack.
How can I control local user volume in Discord by tapping into a local Discord process? I'm happy to make and install a custom browser plugin to do this against a web-based discordapp.com page.
