CaptureStage is a feature that determines the level of document
capture requirements. As soon as the document capture flow starts,
a timer is activated. During the defined time, the configurations
specified in each of the configured stages are applied. It is possible
to define a list of CaptureStages to gradually ease the document capture
requirements over time. This feature exists due to the diversity of
camera hardware in Android devices, preventing the user from getting
stuck in the document capture flow during their onboarding.
