PHP exception on Drupal 9 with: The entity type gdpr_consent_agreement does not have an "revision_created" entity revision metadata key

Problem/Motivation

After installing the module, PHP exception generated and the site is not reachable with:
The entity type gdpr_consent_agreement does not have an "revision_created" entity revision metadata key

Steps to reproduce

install Drupal >9 and install DGPR module

Proposed resolution

EDIT: /gdpr/modules/gdpr_consent/src/Entity/ConsentAgreement.php
AFTER:
* entity_keys = {
* "id" = "id",
* "label" = "title",
* "uuid" = "uuid",
* "uid" = "user_id",
* "langcode" = "langcode",
* "status" = "status",
* "revision" = "revision_id",
* },
ADD THIS:
* revision_metadata_keys = {
* "revision_user" = "revision_user",
* "revision_created" = "revision_created",
* "revision_log_message" = "revision_log"
* },
