How do I detect (or wait for) the client to finish recreating the subscriptions and monitored items after reconnecting to the server?

I'm using the asyncua.Client and during a reconnect to the server it goes through the following states:

| 2026-08-14 11:30:15,629 | INFO | asyncua.client.client | Task-5 | Reconnected successfully (session %s)

I can detect when the client has reconnected (which I have done):

| 2026-08-14 11:30:15,610 | WARNING | opc | Task-5 | state change - UaClientState.CONNECTED - Default OPC Client

and now I want to wait until the subscriptions and monitored items have been recreated:

| 2026-08-14 11:30:15,629 | INFO | asyncua.client.client | Task-5 | Reconnected successfully (session %s)

How do I detect (or wait for) this state?

I was able to accomplish this by subclassing asyncua.Client and overriding the _finalize_reconnect method...

class OPCClient(Client):
	def __init__(
	        ...

async def _finalize_reconnect(self, reused: bool) -> None:
	await super()._finalize_reconnect(reused)
	### do what I want here...
