Oil Filter socket gla250 4matic

I have a 2017 gla250 4matic 2 liter turbo and want to change the oil on it. I have been having a hard time finding an oil filter socket for it. Can anyone point me to one I can buy that will fit it?

Thanks,

Found one on Ali Express, quite cheap, made of aluminum. Hope it arrives and it fits.

Another related question ... Many people talk about the Mann-Filter oil filter coming with all the seals, but no oil plug washer. I got one of those just like that. Can anyone explain why one must replace the oil plug washer on Mercedes cars? Or is that just overdoing an oil change? I have been doing oil changes on other vehicles for decades and have yet to replace an oil plug washer, lol.
