Events are not being dispatched

[ArthurHetem]

Hello, i've been struggling with one thing, i can't get the events to be dispatched and listened.

i added that to my model:
`use AttributeEvents;

protected $dispatchesEvents = [
'status:issued' => OrderIssued::class,
];`

then i added this to my EventServiceProvider $listen array:
OrderIssued::class => [ SendMeliInvoiceXML::class, ],

am i missing something?

thank you
