Add it to your edit page

class EditOrder extends EditRecord
{
    use HasDirtyState;

class EditOrder extends EditRecord
{
    use HasDirtyState;

In my case I wanted to only show the actions when the form is dirty, so use this closure

->visible(fn ($livewire) => $livewire->formDirty)

->visible(fn ($livewire) => $livewire->formDirty)

Note you'll need to add ->live() to the form components

Help Us Improve Filament’s Docs & Education in v4

I think the documentation indexing needs some tweaking. Search for databaseNotificationsPolling and nothing found. Goto this page https://filamentphp.com/docs/3.x/panels/notifications#setting-up-websockets-in-a-panel and you'll see databaseNotificationsPolling('30s') Pretty sure this is a common issue with not finding code that is there. That would be a useful fix.
