Hello mates,
The envato theme check plugin is still showing “The theme appears to use dynamic_sidebars() but no register_sidebar() was found” error.
I hope as per the new WordPress requirements WordPress Requirements Update and New Gutenberg Optimized Attribute Widgets can’t be registered with WordPress theme side as it is Plugin Territory Functionality.

Please correct me if I am wrong
