Magento 2.3 - How to allow selected payment method for selected customer group by Event Observer?

I want selected customer group members only pay via Paypal, how to restrict by using Event Observer.

Hello @Aveeva 

Please follow the below steps to solve the issue:

1. Create events.xml at app/code/Vendor/Extension/etc/
   

   <?xml version="1.0"?>
   <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
       <event name="payment_method_is_active">
           <observer name="disable_payment" instance="Vendor\Extension\Observer\PaymentMethodAvailable" />
       </event>
   </config>

2. Create PaymentMethodAvailable.php at  app/code/Vendor/Extension/Observer/ 
   

   <?php
   namespace Vendor\Extension\Observer;
   use Magento\Framework\Event\ObserverInterface;
   class PaymentMethodAvailable implements ObserverInterface
   {
       public function execute(\Magento\Framework\Event\Observer $observer)
       {
           // you can replace "checkmo" with your required payment method code
           if($observer->getEvent()->getMethodInstance()->getCode()=="checkmo"){
               $checkResult = $observer->getEvent()->getResult();
               $checkResult->setData('is_available', false); 
           }
       }
   }

I hope it helps.

Thank you.
