secrets.json file and the authentication - can I use old one?

[pejotigrek]

I am using GoogleFindMy-HA V1.5.5-4, and while preparing to update to V1.6.0 - I've read about the need of reauthentication.
while I remember that going through this on Windows was a pain, I've started to look for some shortcuts ;) so here's the full question:

in the custom_components\googlefindmy\Auth\ folder of HomeAssistant, I have the file secrets.json and I am assuming that everything inside is what is needed for authentication - is it possible to reuse this file when upgrading and reauthenticating?

the structure is as follows:

{
	"aas_token": "###REDACTED###",
	"fcm_credentials": "{\"config\": {\"bundle_id\": \"com.google.android.apps.adm\", \"project_id\": \"###REDACTED###\", \"vapid_key\": \"###REDACTED###\"}, \"fcm\": {\"installation\": {\"created_at\": 1126.155098977, \"expires_in\": 604800, \"fid\": \"###REDACTED###\", \"refresh_token\": \"###REDACTED###\", \"token\": \"###REDACTED###\"}, \"registration\": {\"name\": \"projects/google.com:api-project-###REDACTED###Q\", \"token\": \"###REDACTED###\", \"web\": {\"auth\": \"###REDACTED###\", \"endpoint\": \"https://fcm.googleapis.com/fcm/send/###REDACTED###", \"p256dh\": \"###REDACTED###\"}}}, \"gcm\": {\"android_id\": \"###REDACTED###\", \"app_id\": \"wp:com.google.android.apps.adm####REDACTED###\", \"security_token\": \"###REDACTED###\", \"token\": \"###REDACTED###\"}, \"keys\": {\"private\": \"###REDACTED###\", \"public\": \"###REDACTED###\", \"secret\": \"###REDACTED###\"}}",
	"owner_key": "###REDACTED###",
	"shared_key": "###REDACTED###",
	"username": "###REDACTED###",
	"integration_stats": {
		"skipped_duplicates": 1871,
		"background_updates": 1583,
		"crowd_sourced_updates": 0
	},
	"adm_token_###REDACTED###": "###REDACTED###"
}

(I've redacted everything that looked like hash/some kind of id, but left all other characters)

ok, so I'll answer it by myself - maybe somebody finds it useful :)

I've started second instance of HomeAssistant [that's the beauty of docker ;)] and installed GoogleFindMy-HA V1.6.0, started configuration and used contents from the custom_components\googlefindmy\Auth\secrets.json file from my main instance.

worked like a charm. no need for additional/new authentication - old json is enough :)
