How to generate links for profile completion with expiry date in NextJS - Supabase

I'm currently working on a NextJS-Supabase project where I have to build a dashboard for some vendors.
Each vendor should be able to login into his dashboard and add his customers to keep track of their informations. The process of adding a customer falls into the following steps :
fill the customer email and submit the request of adding him.
The customer receives an email containing a link available for 5hours.
The link redirects him to a page where he can complete some of his basic information such as address, phone...etc.
Once the form submitted the customer data are updated in Supabase.
I don't know how to implement this in NextJS-Supabase knowing that the customers don't have a user account. Only vendors have a user account and can login/logout.

server side account check - is user registered (backand.com)

i currently stuck on building an account check like whatsapp.
When a user clicks on his smartphone on his/her contacts, it should display, which user has an existing account.
So in theory it should post all user contacts to server, server checks if there is an account with this email adresse and sends the "updated list" back to the client.
Sounds easy, but how do i do something like that :)
Getting the contacts is working, also posting contacts to server.
I had my backend on backand.com and building an app with Ionic/Angular.
This should be very simple.
The core functionality here is based on Backand built in 'users' object, it holds all users you've added to your app, a simple GET to this object will return all your users details including emails.
Now you can add a serverside js action that
gets the contacts details from the client-side app in the request body (as JSON)
does an $http call to the users object ro fetch exiting users.
loops the contacts and search for them in the users array

Mirror API or Glassware - adding an app to contact list

How do I add an app to the user's contact list to be able to share things such as pictures or videos with?
Your Glassware needs to create a Contact for the user once they have added your Glassware. They may later be used as a share target.
See https://developers.google.com/glass/contacts for general information about contacts and https://developers.google.com/glass/v1/reference/contacts for information about how to create contacts from your Glassware and manage the contacts your Glassware creates.
Once you create a contact, the user will be able to share with it fairly quickly, but they are also able to turn off that share contact from their MyGlass page or app.
