How to get link validation mail in Spring Boot App

Hi everybody,
We use Keyclaok v10.0.2 and keycloak-admin-client.

Actually we send two mails for user to validate his account (One from keycloak and another from our application).

We need to get link of validation account sent by Keycloak to use it in our email sent by our application.
Is that a way to do that with keycloak REST API or via keycloak SPI or any other solution.

thank’s for all.
