High-performance order storage with custom plugin

Hello
The last update of WooCommerce supports High-Performance Order Storage. But that didn’t work with the custom payment plugin and showed the “Incompatible Plugins” error. I’d checked the below links but didn’t show anything about this, and didn’t clear what I needed to add to the custom plugin to make it compatible with HPOS.
