I have a bot that works and one of the commands of the bot is (for this post I've replaced Role IDs with names):

module.exports = {
    name: 'youtube',
    description: "Sends a Youtube Link",
    execute(message, args){

        if(message.member.roles.cache.has('DJRankID')){
            message.channel.send('https://www.youtube.com');

        } else {message.channel.send('Sorry, you dont seem to have DJ Permissions');
        }
    }
}

I'm trying to add assigning the DJ role if they already have another specific role:

module.exports = {
    name: 'play',
    description: "Sends a Youtube Link",
    execute(message, args){

        if(message.member.roles.cache.has('DJRoleID')){
            message.channel.send('https://www.youtube.com');

        } else if(message.member.roles.cache.has('MemberRoleID')){
            message.member.roles.add('DJRoleID');
            message.channel.send('https://www.youtube.com');

        } else if(message.member.roles.cache.has('OfficerRoleID')){
            message.member.roles.add('DJRoleID');
            message.channel.send('https://www.youtube.com');
        
        } else if(message.member.roles.cache.has('LeaderRoleID')){
            message.member.roles.add('DJRoleID');
            message.channel.send('https://www.youtube.com');

        } else if(message.member.roles.cache.has('HelperRoleID')){
            message.member.roles.add('DJRoleID');
            message.channel.send('https://www.youtube.com');

        } else {message.channel.send('Sorry, you dont seem to have DJ Permissions');
        }
    }
}

Youtube command works fine but the Play command does nothing. Bot has Manage Roles enabled. Am I missing something?
