Fatal error: Uncaught ArgumentCountError

Hello, I getting:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function WC_Product_Vendors_Approval::trigger(), 1 passed in /public_html/wp-content/plugins/woo-preview-emails/classes/class-woocommerce-preview-emails.php on line 272 and exactly 3 expected in /public_html/wp-content/plugins/woocommerce-product-vendors/includes/emails/class-wc-product-vendors-approval.php

when I try to preview “Vendor approval”, “order note with customer(vendor)”, and “Order Fulfill status notification”.

I have WooCommerce Product Vendors 2.1.21 installed
WP version 5.6
WC version 4.8.0

Maybe helps for making the plugin better. Cheers!
