Proceed to next step on new page
I'm creating a multi-page walkthrough, and there's a step in the process where the user uploads an attachment into a field (either via click or drag). Once the file is uploaded, the page automatically redirects to the next step in the process (which is choosing settings about the attachment).
Because the page automatically redirects, I cannot use a button to move to the next step, but if I use a click or hover action, the user may not be able to upload the CSV before the next step appears. Is there a way to trigger the next step to appear automatically after the page proceeds?
