Hi @Jimmy_Greaves ,
The prescribed/suggested way of achieving this is to invoke create document validation action , perform rest of the steps (as the bot does not wait just by creation of action, but only when you invoke ‘wait and resume’ activity). This will enable automatic resumption of process as and when user act on the task in action center and you could process data sent from user as per your requirement in the same workflow or different process.
Some getting started templates for DU framework and templates focused on Form Task can give you some ideas. Also please look at snippets in studio (snippets > orchestration)
