Getting data from browsers sessionStorage from microflow

I am currently facing the challenge of accessing the browser's sessionStorage, which in itself shouldn't be pretty simple with a single line of JavaScript called from a nanoflow. But here's the thing: I am coming from a microflow (and I can't change that), so using a nanoflow that calls a JS action is out of the question.   Is it possible to access the browser's sessionStorage without using a nanoflow/JS combination?

sessionStorage exists on the client side, whereas microflows are executed server side, so there is no way to interact with sessionStorage from a microflow / Java action. You would have to send the data from the client to the server and then pick it up server side, but then you would have to use nanoflow / Javascript.
