Encapsulate display (for support for both v2 /v3)

Hello, since your plugin doesnt support native to the wp_login_form() – which I believe it should and be easy to support.

the configure of which version is private in your class – which is ok you do:

$sgrDisplay = $this->version === 3 ? ‘v3Display’ : ‘v2Display’;

so maybe just have a function

public function display() {
     $sgrDisplay = $this->version === 3 ? 'v3Display' : 'v2Display';
     $this->$sgrDisplay();
}

and change the 231 line

  add_action($sgr_display, [$this, $sgrDisplay]);
  
  to

  add_action($sgr_display, [$this, 'display' ]); 

even better if you can add support to the wp_login_form(), which is something similar to that

    add_filter( 'login_form_bottom', function( $html, $args ) {
		if ( !class_exists( 'SimpleGoogleRecaptcha' ) ) return( $html );
		$recaptcha = SimpleGoogleRecaptcha::getInstance();
		ob_start();
		$recaptcha->enqueueScripts();
		$recaptcha->v3Display();
		$html .= ob_get_clean();
		return( $html );
	}, 100, 2 );

and maybe just allow to hook using filters to your

$sgr_display_list
