Since the release of 5.x, the intercom-php documentation/readme has been completely useless. Going from the client initialisation (#381) to the request building, a lot of things have been type hinted and documentation not updated at all.

A migration guide would actually be amazing considering it's very painful to migrate going from one endpoint to another and manually looking for the types.

Simple example :
The contacts()->create() method now accept any of these objects instead of an array :

• CreateContactRequestWithExternalId
• CreateContactRequestWithEmail
• CreateContactRequestWithRole

So instead of

contacts()->create([
    'email' => 'test@example.com',
    'last_seen_at' => now()
])

you need to do the following :

contacts()->create(new CreateContactRequestWithEmail[
    'email' => 'test@example.com',
    'lastSeenAt' => now()
]))

Note that attribute names have also been changed from snake case to camelCase.

Any update is greatly appreciated.
