Copying/Exporting assets from Content Browser with Widget

Hi everyone,
I’m working on some tools to simplify/automate a virtual production workflow. For one of them I would like to create an editor widget that lets me create a custom folder structure and copy/migrate some level sequences in them to ve versioned and edited. Another widget I’m trying to figure out is to export fbxs from sequencer tracks to disk by inputting the name of the levelsequence/subsequence. In both cases I get stuck when I try to access the content browser selection from the graph, or whenever I try to cast anything from my editorwidget.
What would be the best approach at doing something along those lines? I’ve been trying to make event dispatcher work but to avail as well.
Thanks in advance,
