Bug Description

In the Thank with Google PHP module code, we are using the wp_get_sidebar function which was introduced in WordPress 5.9.0.

This is causing the site to be non-functional for pre-5.9.0 when Thank with Google is enabled.

Steps to reproduce

Using a pre-5.9.0 version of WordPress:

1. Enable and set up the Thank with Google module.
2. Upon refreshing the page the error will be shown as per the screenshot below.

QA Update: ✅

Verified:

• Switched back to the latest version of WP and ensured that I could still connect TwG with no errors.
