I didn’t open the attachments but you can manually make a workflow by making some input go to a Run Script. Here is the script that works (Your personal token is here Login - Dynalist )
TOKEN="dooooooooooooongs"
CONTENT="{query}"
curl --header "Content-Type: application/json" \
--request POST \
--data "{\"token\":\"${TOKEN}\",\"content\":\"${CONTENT}\"}" \
