How do i give a user a role with ‘/’ command with discord.js v14

I was trying to give myself a role when executing a “/” command, and ive tryed many solutions from stackoverflow but none of them work for discord.js v14. Im pretty new to js.

tryed:

const guild = interaction.guild
const role = guild.roles.cache.find(role => role.name === 'Admin');
var dcuser = interaction.user.id
dcuser.roles.add(role)

Got:

TypeError: Cannot read properties of undefined (reading ‘add’)
