My EQA does not make any artificial noise. (AVAS)

Hi I have read that all EV Mercedes have AVAS.(Acoustic vehicle alerting system) However,my 300 EQA 2022 I bought second hand 7 months ago does not make any sound at all when moving. And I’m talking about speeds under 30 km. Only when revering it makes a “clang clang”noise. I’m in EU.Greece. Can you please confirm anyone that indeed in some places cars might not come with this feature?
