Hi,

I'm implementing a multi-page dash app and I thought it would be nice if the user could change between pages while waiting for the upload to finish.
Dash introduced Background Callbacks (https://dash.plotly.com/background-callbacks) where (after some extra work on setting up Celery and Redis) callbacks with the 'background' parameter set to True execute their task in the background when triggered.

I was wondering if there's a way to make use of this Dash Feature with dash-uploader. The du.callback does currently not take a background argument either.
It would be really cool if the user could chose a file and the file upload would be moved to a background task.

I don't know how easily this is realizable. If anyone knows a workaround that would be highly appreciated as well :)

Best,
Tamara
