Finally, you'll have to create a new user from IAM. Name the user appropriately and give programmatic access.
Afterwards, click the button. From the "Attach existing policies directly" tab, find and check the "AmazonLexFullAccess" policy.
Click the button. Feel free to skip these two steps and click on and then the button.
From the final screen, copy the "Access key ID" and "Secret access key" to our connector.
