I have a Lex bot where it collects a value for a slot "name". Then in the lex interface, for fulfillment, I selected "return parameters to client", I assume this means it will return intent and slot values to Connect when I add a "get customer input" from lex block in Amazon Connect? Then I want to check if the value from the slot is equal to a certain name, so I used "check user attributes" block, but things seem not working properly. Is it the way that I reference the slot value wrong? I used "$.Lex.slots.name" Please point out if my understanding is wrong. Thank you.
