How to issue a role on a specific server?

Question

Node.js

client.on('guildMemberAdd', async (member) => {
    var role = member.guild.roles.cache.find(role => role.id === "784364508432695296");
    member.roles.add(role);
})

made such a system, the question is how to make this role auto-provision current on a specific server, and not on all servers where there is a bot?
