I have no option to load the local JSON file
**Which version of the plugin are you using?**
[ ] Data Populator for Sketch
[x ] Data Populator for Adobe XD

**Describe the bug**
The only data source option available to me in XD is `inherit` … but there's nothing to inherit.

**To Reproduce**
1. Attempt to use the plug-in
2. Get nowhere

**Expected behavior**
1. Attempt to use the plug-in
2. It lets you choose a local JSON file

**Environment (please complete the following information):**
 - macOS 11.6 (20G165)
 - Adobe XD 44.1.12.5 arm64
 - Plugin Version 4.0.3

**Additional context**
I have a local JSON file and I'd love a way to populate the disaster that is XD. My main design is built out as components, but I'll break them apart if it means I can use real data. Right now, I can't figure out how to make it work no matter what. This project is making me miss Sketch desperately.
