Add filter policy to SNS subscription

Filtering SNS messages require setting a filter policy on top of the subscription's connection.

Add filter policy to SNS subscription

1. Click on the SNS's sourced connection you wish to add the filter policy.
2. Set Property, Type, Operator and Value of the filter policy rule.
3. Click SAVE to finish editing the connection.

This will create a filter policy on top of the SNS subscription. The filter policy applies to the SNS's message attribute MessageAttribute. Check out AWS docs for further reading.
