How do I send a rbxl file

So this is a bug report plugin, I am making with @LandnBlu , and I made a plugin where you enter data and it goes to discord by a webhook proxy, the thing is in bug report, you need to attach a repro file like a place where its happening, so the thing is the info is going to discord and I am able to see it, and I also made an import button using PromptImportFile(), and it gets imported to plugin and shows “Imported testplace.rblx”

How do I send the rblx imported file to Discord? or any way to send?

Uploading files to webhooks is documented here.
