Sitecore Commerce - Refresh Commerce Cache - This operation is not available unless admin mode is enabled: FLUSHDB

In one of the eCommerce application, Sitecore Commerce 10.1.1 is being used. After few infrastructure consolidation, testing out Refresh Commerce Cache option in CM resulted in the below error. 

Based on the exception, we found that we can add AllowAdmin option to the Sitecore Commerce Redis Connection string. All Commerce related settings are available in this folder - \App_Config\Include\Y.Commerce.Engine.

In Sitecore.Commerce.Engine.Connect.config, allowAdmin=true configuration is added to the Redis Connection string. Refreshing the commerce cache worked without an error.
