How can I create a notification entity with Rules module

Question

I have installed a notification system and I want to create notifications with Rules when a project content is updated to waiting for approval status.

The rule looks like this:

uuid: 3165768f-15f5-4c35-a7e6-3f862b526f10
langcode: en
status: true
dependencies: {  }
id: project_updated
label: 'Project updated'
events:
  -
    event_name: 'rules_entity_update:node--project'
description: ''
tags: {  }
config_version: '3'
expression:
  id: rules_rule

    id: rules_condition

    context_processors:
      operation:
        rules_tokens: {  }
      value:

      token_entity: ''

    context_processors:
      token:
        rules_tokens: {  }
      token_entity:
        rules_tokens: {  }
    provides_mapping:
      token_value: unix_time
    action_id: rules_token_get_token_value
      -
    id: rules_action
    uuid: 92aeaa68-c475-4ae7-97aa-2f74d72b89ff
    weight: 0
    context_values:
      user_id:
        - '1'
      provider_id: project
      notification_type: waiting_for_approval
      created: '{{ unix_time }}'
      title: 'New project waiting for approval: {{ node.title }}'
      priority: '3'
    context_mapping: {  }
    context_processors:
      user_id:
        rules_tokens: {  }
      provider_id:
        rules_tokens: {  }
      notification_type:
        rules_tokens: {  }
      created:
        rules_tokens: {  }
      title:
        rules_tokens: {  }
      priority:
        rules_tokens: {  }
    provides_mapping: {  }
    action_id: 'rules_entity_create:notification'

It's getting triggered and it's actually being executed the reactions (actions) also. However it does not create the entity, and I don't receive any error in the Recent log messages. With a little xdebug I've found that the tokens are replaced.
unix_time to a UNIX timestamp
node.title to the saved node title.

However, for some reason, the notification entity is not being created. How can I create an entity with rules if not like this?

Most likely you just need to add a "Save entity" action. Entities that are part of the context (in this case the project node) are automatically saved, but any entities you create during the rule may need to be explicitly saved.
