What can this plugin do for me?

I tested the plugin yesterday, and I followed the instructions, the transfer worked, and at the end I long pressed on the file, chose "extract onyx file" but nothing happened.
I opened the file, and there is nothing different, as if I opened it without the plugin.
Because of the "-----" - lines in between, the text gets bold as always.

I tested it on Onyx Boox Note Air 2 plus, and Windows 10 with Obsidian v.1.5.10
I tried it either on my Boox-device, and also on my PC.
I am really sorry, but the plugin does exactly nothing on my devices.
