Replace all the Lorem Ipsum from a Bricks' template with ChatGPT content

This query replaces all Lorem Ipsum in the text elements inserted in a Bricks page from a template with actual content created using ChatGPT.
To create the content, the prompt to ChatGPT provides the title of the heading element from that same container.
This query requires the Bricks extension to be enabled.
The query requires the following variables:
$customPostId: The ID of the Bricks custom post to update
$openAIAPIKey: The API key for the OpenAI API
