How correct is it to use a facade for commands?

Question

PHP

To implement Application Layer scripts, I use commands and handlers,

$commandBus->handle( new LoadFileFromSource($loadParamDto));

and everything would be fine, but there is some problem in using, let's say there is no convenience in documenting when you connect the service and see public methods, in this case you have to open the documentation (wiki) or the source directory to see the entire list of commands and handlers.
Therefore, I came to the implementation of facade classes in each logical package, which provides an API to the package commands.
$fileFacade->loadFileFromSource($loadParamDto);

I would like to know how you document commands, events in your systems, how kosher is it to use a facade?
