I had a similar desire and ended up writing a little solution that I had a question about here. I wanted something that used the native system dialog and that little code snippet has served me very well.
*edit: To be clear I did very little of the writing for this snippet. It’s based off the file dialog example in QML.jl. I just tweaked it a bit and converted it to one self-contained solution (code wise atleast, QML.jl obviously needs to be installed).
