What’s the best way to combine an action outside of the UI with an action in the UI?


Working on a picking flow for a warehouse app and I’m having trouble translating the following flow into design

Go to space –> Scan space –> Scan product –> Enter # of units picked

thinking something like this, but I feel like it’s missing feedback needed to direct the user thru the flow without making them think – also, with this flow I’m not sure where to add the input field so that user can enter # units picked

Thank you for your help.
