This is great and a deep dive into the Framework without a ton of examples available. Thank you! ✨

I'm generally torn on if we should have these expand/flatten/mutate functions returning (value, diag) or passing it in: perhaps Hashi will provide some idiomatic guidance when they get their examples updated. 🤔

A few nit-ish suggestions, but all are non-blocking.

Suggested change

	detailsObj := map[string]attr.Value{"pagerduty_severity": types.StringValue(s)}
	return []attr.Value{types.ObjectValueMust(models.NotificationRecipientDetailsAttrTypes, detailsObj)}
	return []attr.Value{types.ObjectValueMust(models.NotificationRecipientDetailsAttrTypes,
	map[string]attr.Value{"pagerduty_severity": types.StringValue(s)})}

[jharley]

Nit-ish, but I think this should be singular

Suggested change

	var NotificationRecipientAttrTypes = map[string]attr.Type{
	var NotificationRecipientAttrType = map[string]attr.Type{

[jharley]

Same as above

Suggested change

	var NotificationRecipientDetailsAttrTypes = map[string]attr.Type{
	var NotificationRecipientDetailsAttrType = map[string]attr.Type{
