Use REST API to modify shortcodes

Can I use the REST API to modify a shortcode? Seems not to work… (I changed the show_in_rest to true already). Here’s a snippet of my python code.

def update_wordpress_post(html_content):
    wordpress_url = f"{rest_api_endpoint}{post_id}"  # REST API URL for creating a post
    username = "username"
    password = "application_pwd"

    # Prepare the data for the request
    data = {
        "title": "name_of_the_shortcode",  # Set the title of the post
        "content": html_content,  # The generated HTML content
        "status": "publish"  # Publish the post immediately
    }

    # Make the POST request to the WordPress API
    response = requests.post(
        wordpress_url,
        json=data,
        auth=HTTPBasicAuth(username, password)  # Basic Auth using username and app password
    )
