How do you add a new slash command without having to kick and re-invite the bot to each server it's in?

To make a slash command you do this:

from discord_slash import SlashCommand

slash = SlashCommand(bot, sync_commands = True)

@slash.slash(name='command name', description='commands description', guild_ids=[#guild id's]):
    #CODE

If you delete the "guild_ids" part then it works in all servers but needs to be kicked and re-invited when making a new one.

On the other hand if you have a guild id in that list it will auto update but that means you have to add every server id to that list which does not work if I want this to be a public Discord Bot.

If you try doing this:

from discord_slash import SlashCommand

slash = SlashCommand(bot, sync_commands = True)

guilds = []
@bot.event
async def on_guild_join(guild):
    #append the guild id when it joins a new server
    guilds.append(guild.id)
@slash.slash(name='command name', description='command description', guild_ids=guilds)

It won't work because it only refers to what the list is at the start. It won't get updated even if the list has changed

Is there anyway to make this easier/automatic?

also if you know the MEE6 bot, the slash commands are there right after you invite the bot so that's basically what I'm trying to do.

Solution

Your slash commands are updated automatically every hour. But when you invite the bot its commands create for guild immediately (if your bot has manage_commands permission).
