App Engine Starter License Access to Task-Extended Tables

Can Starter License users create and update records in custom tables extended from the Task table?

Background & Details:
I have a question regarding ServiceNow licensing and custom table permissions. We are using Starter Licenses for end users and have created custom tables extended from the task table (e.g., x_custom_task).

1.Current Setup:
    Custom tables inherit fields from task (e.g., number, state, assignment_group).
    We need end users to perform basic actions like:
        Creating new records in the custom table.
        Updating specific fields (e.g., adding comments, changing status).
2.Concerns:
    Does the Starter License inherently allow data manipulation (INSERT/UPDATE) in custom tables extended from task?
    Are there specific roles/permissions (e.g., custom roles, ACLs) that need to be assigned to Starter License users to enable these actions?
    Are there any licensing restrictions or best practices to consider when granting such permissions?

3.Reference:
    We reviewed the Starter License documentation but couldn’t find explicit guidance on custom table operations.

Request:
Could you clarify:

    Whether Starter License users can natively create/update records in task-extended custom tables.
    If not, what configurations (roles, ACLs, License, etc.) are required to enable these capabilities.
    Any potential licensing or security implications of such configurations.

Has anyone successfully implemented this?

Thank you for your assistance!
