Lex bots are not populating in Amazon Connect Instance

We have created a bot and published and trying to invoke from Amazon Connect instance. Lex bots are not populating in the drop down. Is there any configuration change we need to do?

You need to add the bot to your Amazon Connect instance before you can make use of it in your contact flow. This is done in the Amazon Connect instance configuration within the AWS console (not the Connect UI). See the section called “Add the Amazon Lex bot to your Connect instance” in this doc for specific steps.
