Which DAC/amp is in this UGreen dongle with charger input?

Ugreen charging dongle

I bought it for the convenience of charging while listening and I found the subjective audio performance to be on par with the Apple dongle.
Is there a way to find out what's actually inside?

Yes. Open it up and look at the chips' inscriptions.
