Call a SKSE plugin function from the console

[onrdev]

I downloaded example plugin from https://github.com/xanderdunn/skaar/releases/tag/plugin3 .I compiled and copied to Data/SKSE/Plugins folder. In My Games/Skyrim Special Edition/SKSE folder MyPluginScript.log has been created.It contains these lines:

 

MyPluginScript

MyScriptPlugin loaded

Register Succeeded

If i start skse_loader and write to console "MyTest" or "MyScriptPlugin.MyTest" it gives "unknown script reference" error.I want to call skse plugin functions from the console(papyrus).What am i doing wrong?Thanks.
