GuildMemberUpdate only fires when my bot's roles are modified.

client.on(Events.GuildMemberUpdate, (oldMember, newMember) => {
    // If the role(s) are present on the old member object but no longer on the new one (i.e role(s) were removed)
    const removedRoles = oldMember.roles.cache.filter(
        (role) => !newMember.roles.cache.has(role.id)
    );
    if (removedRoles.size > 0) {
        console.log(
            `The roles ${removedRoles.map((r) => r.name)} were removed from ${
                oldMember.displayName
            }.`
        );
    }
    // If the role(s) are present on the new member object but are not on the old one (i.e role(s) were added)
    const addedRoles = newMember.roles.cache.filter(
        (role) => !oldMember.roles.cache.has(role.id)
    );
    if (addedRoles.size > 0) {
        console.log(
            `The roles ${addedRoles.map((r) => r.name)} were added to ${
                oldMember.displayName
            }.`
        );
    }
});
