Whatsapp integration flow

Hello, - I created a flow that works perfectly on the web (without any issues). - I wanted to test this flow on WhatsApp (to see if it's really what I need). - In the test tab, there's an option to select "WhatsApp" and send it to the desired number. - When I do that and start the chat, I receive the initial message of the flow. - However, when it reaches the next part of the flow, where I have to enter a phone number, for example, the flow apparently doesn't continue, and I don't receive any more messages. - I wanted to be able to do this test to see if it's really the product I'm looking for. - But I'm stuck at this point. Thank you.
