Deprecated warning

Hi Oliver,

I get a warning (upon load) when visiting a post or page in the block editor, related to your plugin:

Deprecated: The PSR-0 Requests_... class names in the Requests library are deprecated. Switch to the PSR-4 WpOrg\Requests\... class names at your earliest convenience. in 
See this temp screenshot.

• WP version 6.5
• I have the Twenty Twenty-One theme active
• Have deactivated all plugins except Options for Twenty Twenty-One
• Server is running PHP 8.1
• Same issue in local install (WampServer) and live site
• Turned debugging on via wp-config:
  define( ‘WP_DEBUG’, true );
