It seems like you code against a concrete implementation and not the interface Spatie\SlashCommand\HandlesSlashCommand as the method canHandle() does only exist in the following implementations of said interface: Spatie\SlashCommand\Handlers\BaseHandler, Spatie\SlashCommand\Handlers\CatchAll, Spatie\SlashCommand\Handlers\Help, Spatie\SlashCommand\Handlers\SignatureHandler.
