Thank you for your patiance & for your question,
When the bot application receives the event via the datafeed, when the form button has been submitted - you will be required to invoke the bot application logic to send an event or message to the analyser service endpoint.
Here is an example condition and what it might look like:
'if form value = true then...<app logic>'
You may be able to also use a webhook in the scernario you have described to respond to the form button event.
Please let us know if you have any questions or comments.
