Few minutes in ETKA and I think that I found it. The most promising one is 3G0973708 (blue), but there are also 3G0973708A (white), 3G0973708B (gray) and 3G0973708C (violet) variants. ETKA says that 3G0973708 is used in Skoda Enyak for Keyless and its door handle (8Y0959121) indeed has 8-pin connector
Edit. Skoda Enyak and Octavia probably uses 3G0973708A (white) which would match color of a connector in the door handle.
