Understanding local file uploading/downloading combining Solara and Voici

[Justyouraveragehomie]

Hi there, im working in Voici at the moment but its unclear to me whether or not I can load files in and out of a static Voici web app using ipywidgets (since tkinter is not available for the kernels).
I saw that Solara has a file download option: https://solara.dev/documentation/components/output/file_download#simple-usage
As an example, if I were to create a Voici web app that uses opencv to load in a local file to be processed, would I be able to use Solara to do this? Im also wanting to save the processed image. Hoping for all browsers.
So to clarify, I do not want to preload any files into my Voici build, but instead access local files from the device that the static web app is running on using Solara.
