Dynamic dropdown on Custom connector doesn't work on Test window

Question

I have created a custom connector from scratch & used a dropdown which is configured as a operation. That operation doesn't apply at that parameter in the test window. How do I check it out them? I have checked them at Swagger Editor. It shows as below 

• name: teamId

   in: query 
  
   required: true 
  
   type: string 
  
   description: Team ID 
  
   x-ms-dynamic-values: 
  
       operationId: GetProductList 
  
       value-path: teamId 
  
       value-title: teamId 
  
           parameters: 
  
               Accept: 
  
                  parameter: teamId
