For folks with write access to discordjs/discord.js, by leaving a comment on any PR:

@discord-js-bot pack this

the bot should leave a 👀 reaction on your comment, after which a publish-dev workflow will be triggered. Once that's done, a comment will be left indicating success. If you receieve no feedback after a reasonable amount of time, it's possible the workflow failed, or that the bot is open.

The bot can also be summoned by an existing comment via edits. Note that @discord-js-bot pack this must be the start of the comment.
