I tried to make self role option for my server, but the roles aren't getting added, even the console isn't showing any error. Please help me!! My code:

client.on('MESSAGE_REACTION_ADD', (rGuild, rChannel, rMessage, rMember, rEmoji) => {
  if((rMessage.id) == '...........'){
    if((rEmoji) == '🇲'){
      (rMember).roles.add((Array.prototype.concat.apply([], client.guilds.cache.array().map((g) => g.roles.cache.array())).find((role) => role.name === 'Man')));
    }

    if((rEmoji) == 'W'){
      (rMember).roles.add((Array.prototype.concat.apply([], client.guilds.cache.array().map((g) => g.roles.cache.array())).find((role) => role.name === 'Woman')));
    }
  }
})
