I'm in need of help registering for all guilds globally, can someone assist me?

Question

I'm looking to register for all guilds globally instead of registering for just my guild ID, just so I can use slash commands in my friend's server (plus any other server it's in), yet I don't know how. I'm a bit new to discord.js.

I was wondering if someone could help me register for all guilds globally...

Extra information - I'm following reconlx's Discord.js v13 tutorials.

This is the part of my code which I need help looking at and modifying. There's a line in his command handler talking about registering for all guilds at await client.application.commands.set(arrayOfSlashCommands);, yet I'm not sure what it means...

client.on("ready", async () => {
        // Register for a single guild
        const guild = client.guilds.cache.get("938823675535319050")
        await guild.commands.set(arrayOfSlashCommands).then((cmd) => {
            const getRoles = (commandName) => {
                const permissions = arrayOfSlashCommands.find(
                    (x) => x.name === commandName
                ).userPermissions;

                if(!permissions) return null;
                return guild.roles.cache.filter(
                    (x) => x.permissions.has(permissions) && !x.managed
                );
            };

            const fullPermissions = cmd.reduce((accumulator, x) => {
                const roles = getRoles(x.name);
                if(!roles) return accumulator;

                const permissions = roles.reduce((a, v) => {
                    return [
                        ...a,
                        {
                            id: v.id,
                            type: 'ROLE',
                            permission: true,
                        },
                    ];
                }, []);

                return [
                    ...accumulator,
                    {
                        id: x.id,
                        permissions,
                    },
                ];
            }, []);

            guild.commands.permissions.set({ fullPermissions });
        });

        // Register for all the guilds the bot is in
        // await client.application.commands.set(arrayOfSlashCommands);
    });

Looking forward to some solutions, if you could assist, it would help a lot.

You can register global commands using the Client.application.commands.set() method, passing in an Array of ApplicationCommandDataResolvables into the method. However, please be aware a caveat of global commands is that they take up to an hour for changes to reflect across Discord.

See this:

client.application.commands.set(commands)
// ^^^                          ^^^^^^^^
// Client is your Discord.Client  Commands is the list of commands
