I’d be really surprised if the 245 and 300ps versions of the engine have different oil recommendations.
My 245 GTI (MY21) has no sticker under the bonnet that specifies oil, just an image that references the manual (which of course says to refer to your dealer for the correct grade).
VW do change their minds during the life of a particular engine model but my local VW recommend and supplied Shell Helix Ultra 0W-30 for mine.
