How to confirm Email when registering through the application?

Question

Mobile development

Good evening everyone!
I am now describing a flow for registering by email through a mobile application. The customer wants to implement such a registration flow:
1) at step 1, we fill out the form with basic information about ourselves;
2) we get to an intermediate screen where we are invited to open the letter and click on the login link
3) open the letter, click on the link and redirect back to the application;
4) in the application after the redirect, I go to the second step of registration and am considered a verified account.
I'm wondering if it is technically possible to implement such a registration option
