Set a settings page field from external api

I have a settings page for business details (business-data) with a bunch of custom fields (business-settings). I would like to populate specific fields (rating, review) with data generated externally from an API (Google Places API) that is linked to the (place-id).

I have the following code that works to echo it onto a page using short code but am a bit lost as to how to output it to the location described previously. Could you please help point me in the correct direction? Thanks

function display_google_places_results()
{
    // Replace with your API key
    $api_key = "APIKEY";

    // Replace with the place ID or name and location
    $place_id = "PLACEID";

    // Construct the API request URL
    $url =
        "https://maps.googleapis.com/maps/api/place/details/json?placeid=" .
        $place_id .
        "&key=" .
        $api_key;

    // Make the API request
    $response = wp_remote_get($url);

    // Check if the request was successful
    if (!is_wp_error($response)) {
        $body = wp_remote_retrieve_body($response);
        $data = json_decode($body);

        // Extract the star rating and number of reviews
        $star_rating = $data->result->rating;
        $num_reviews = $data->result->user_ratings_total;
        $business_name = $data->result->name;
        $google_profile_url = $data->result->url;

        // Display the results
        echo '<p><a href="' .
            $google_profile_url .
            '">' .
            $business_name .
            "</a></p>";

        echo "<p>Star Rating: " . $star_rating . "</p>";
        echo "<p>Number of Reviews: " . $num_reviews . "</p>";
        update_field(
            "reviews",
            $value . " (" . $num_reviews . " Reviews)",
            get_option("business-settings")
        );
    } else {
        // Handle errors
        echo "Error fetching Google Places data.";
    }
}

add_shortcode("google_places_results", "display_google_places_results");
