Can't verify proxy contract at @openzeppelin/[email protected]

[quThinh]

I'm having a transparent upgradeable contract that deployed by @openzeppelin/[email protected]. But when I go to deeper in the library. I found out that the proxy contract (which is AdminUpgradeabilityProxy) doesn't have implementation. It only has json file that contained abi, bytecode and some other information. As far as I'm concerned, this is not enough for me to verify

So I want to ask if contributor team know the which version of Openzeppelin contract of library above and what is its compiler option to get the AdminUpgradeabilityProxy's abi in the file.
If not, is there anyway for me to verify this proxy contract?
