How to use zak token join meeting

I created a meeting and the web side uses the ack token to join the meeting。

ZoomMtg.join({
  sdkKey: sdkKey,
  signature: signature, // role in SDK Signature needs to be 1
  meetingNumber: meetingNumber,
  passWord: passWord,
  userName: userName,
  zak: zakToken, // the host's zak token
  success: (success) => {
    console.log(success)
  },
  error: (error) => {
    console.log(error)
  }
})

I created a conference using authorization verification
Participants join the conference with a role 0 signature.
The moderator joins the conference with role 1 signature.

expect:
Only the host can start the meeting

actual:
Participants can start a meeting.
