How to find google account of locked phone we found to return it to owner We found a phone in the park and would like to return it to the owner.

Samsung Galaxy S10
Battery was dead
Charged the phone, its locked by pin code, not registering on network
Took off SIM card and installed to another phone to wait and receive a call from someone/owner
SIM card not registering in the network, looks like it was locked/reissued

Is there any way to find Android or Samsung account tied to this phone, so we can send an email to owner to return it?
Thanks.
Keep mobile charged. Owner may send message or call. Try to restore mobile, it ask for google account. May be you can see email id.
Find IMEI number, contact service center for owner or police station for lost complaint.
Try to backup mobile use adb of usb debugging is on. You can find some contact from mobile.
