Error Message: (node:12160) and problem with an await function - discord

Question

My Problem is that I'm getting the following error Message:
(node:12160) DeprecationWarning: The message event is deprecated. Use messageCreate instead(Use `node --trace-deprecation ...` to show where the warning was created)
I know that there's a solution for this on this Site but my problem is that my await function is not working when I try to change the .send({ embeds: [embed] }) to message.channel.send({ embeds: [embed] }); and i don't know how to change the embed so my await function is working and the error resolves.
if (message.content.startsWith("!Suggestion")) {
var str = message.content.slice(" !Suggestion".length);
const embed = new Discord.MessageEmbed()
.setThumbnail('Png')
.setTitle("Suggestion")
.setColor('#151515')
.addFields(
{ name: "Person, with a suggestion:", value: `<#!${message.author.id}>` },
{ name: 'Suggestion:', value: `${str}` },
{ name: 'Channel:', value: `${message.channel}` },
)
.setTimestamp()
.setFooter("You can vote for the suggestion with the emojis on the bottom")
await message.guild.channels.cache.find(c => c.name === 'Suggestion')
.send({ embeds: [embed] })
.then(embedMessage => {
embedMessage.react("✅")
embedMessage.react("❌")
});
message.delete();
}
});

It looks like you updated to Discord.js V13 and there are a lot of changes.
The warning you get is about the on message event.
On v12 it was:
client.on("message", ...);
and now on v13 it is:
client.on("messageCreate", ...);
Check https://discordjs.guide/additional-info/changes-in-v13.html for all the changes in the newest version.
You will have to update your code according to the changes.
