__Restart and Reload__

The user can __Restart__ a conversation or session in the Tryout to reset, for example, Global variable values in order to keep testing a certain Flow making use of those variables. __Reload__ can be used to recreate the Tryout engine instance, this allows to reload the entire solution and fetch any changes performed by collaborators which are not automatically loaded into the current Tryout engine instance although they are visible when opening a document (i.e. a Flow).
