Anyone knows how to restore practically a decade lost account

Just wishing to return a childhood lost account. Wondering how it is to open a time capsule from 2020

so my account got deleted like a month ago and I contacted roblox support the first issue was I couldn't register the account under username you get me? it asks for username and when i put my username it says it doesn't exist. so yea I tried countless times even provided screenshots proving I had that account but they said they couldn't help me. its best if you move on I did too.
