Export custom token to metamask

Hello, I added a token on my wallet based on ERC20, I’d like to export those tokens to metamask but I am not able to find any private keys in order to do so, also the Mnemonic tool only works with listed or relatively popular tokens so I’m not able to export my tokens without sending it.

If you understand the risk you can get the private keys here:

Please be advised that doing so will expose both your recovery phrase and private keys.
