Can't Access My Snapchat Account Due to Old Phone Number

I'm attempting to access my Snapchat account after a considerable period, but I've updated my phone number since my previous usage. Currently, the verification code is being sent to my previous number, which is causing a hindrance in completing the verification process.

It would be greatly appreciated if you could assist me in resolving this matter so that I can regain access to my account. Could you please help me with updating my phone number or finding an alternative method to verify my identity? Thanks!
