I'm trying to make a system in discord.js version 12 where if you have my vanity invite in your status, you get a supporter role

Whenever I try this it always says TypeError: Cannot read property 'find' of undefined

Here is my code

const roleID = "MyRoleID"
const inviteLink = "discord.gg/MyVanityInvite"

client.on('presenceUpdate', (_oldPresence, newPresence) => {
  const member = newPresence.member
  if (member) {
    // Ignore members who already have the role
    if (!member.roles.cache.has(roleID)) {
      console.log(newPresence)
      const customStatus = newPresence.activities.find(activity => activity.type === 'CUSTOM_STATUS').state
      if (customStatus) {
        if (customStatus.includes(inviteLink)) {
          member.roles.add(roleID)
            .catch(console.error)
        }
      }
    }
  }
})

If I try to log the newPresence is logs an array
