can't find export/import button

[ImMorrow]

I followed the tutorial step by step and I couldn't find the export or the import button.

BTW, I tried 2.83, 2.93 and 3.1
none of them worked.

Which version of the plugin do you try to install?
The 0.5.2 release and the master branch are for Blender 2.78. There are branches for 2.8x and 2.9x, but I don't know what their status is, they could be incomplete.
