updateEmail for passwordless accounts

Hi, I am trying to implement email update using OTP, there is not password associated with the account. One solution I found online is creating appwrite function https://appwrite.io/threads/1113539995991539814. Is it doable without creating this function? I am limited to 2 functions on free account and already consumed those.

i dont think so, you will need some kind of custom server logic on how you want to handle auth for the user in this case
