Discord.js: Trying to create a message system between two different servers with a discord.js bot

I am trying to get my bot to read messages from a channel in server 1 and send the same message with some added content to a channel in server 2 and vice versa when a message is sent in server 2 in the same channel.

Right now the bot can only read one message and send it perfectly but after that the bot sends the message back to the same channel.

Here is my code below:

client.on('message', message => {
  if(message.author.bot) return;
  if(message.channel.id = "735085499571765288"){
      var messageContent = message.content;
      client.channels.get('735084968476278805').send(`A Ruse Kid Said: ${messageContent}`);
  }
});

client.on('message', message => {
  if(message.author.bot) return;
  if(message.channel.id === "735084968476278805"){
    var messageContent = message.content;
    client.channels.get('735085499571765288').send(`A High Kid Said: ${messageContent}`)
  }
});

Any help or advice appreciated. Thanks for your time.

if (message.channel.id = "735085499571765288") {

if (message.channel.id === "735085499571765288") {
