The "commerce_stripe_payment_request_button" plugin did not specify a "offsite-payment" form class

Same error with
Drupal 9.5.5
Commerce : 2.33
Commerce Stripe: Payment Request Button 3.5.4

Anyone find a solution ?

I have a similar problem. We have chosen the Commerce Stripe - payment request button as checkout flow, but the error still persist. The Stripe payment is an option on the site to choose from, but we don't see a Stripe button on the checkout pages.

Environment:

PHP 7.4.33 (tried on 8.1 also without any success)
Drupal 9.5.11
Commerce 8.x-2.33

I see the successful API requests on the developers dashboard on stripe.com Anyway after completing the order the site shows an error and the drupal log outputs:

Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException: The "commerce_stripe_payment_request_button" plugin did not specify a "offsite-payment" form class in Drupal\Core\Plugin\PluginFormFactory->createInstance() (line 41 of /var/www/domain.com/public_html/core/lib/Drupal/Core/Plugin/PluginFormFactory.php).
