You can take a look at the Fallback Policy. There you can define a threshold of confidence under which a fallback action is executed. Then, in your example, the abort intent would be classified but not immediately abort you form and instead resulting in your fallback action.
I know the Fallback Policy but when the Fallback Action is triggered I still cannot continue the form. When I would re-enter the form (in stories) and input the same value, the Fallback Action is going to be triggered again. So this is not a solution for the issue. Thanks anyway!
