Autocorrect: Different behavior for MAC and Windows?

Hi

I´ve seen two cases regarding the option to deactivate the autocorrection, but this is not available in the newest Zoom Client for me in Windows 10.
Is there an other way to disable the autocorrect.

The colleagues that are using MAC OS can open with right click in the textfield the options for the deactivation but once deactivated but this isent persistant. And is this really needed to dactivate in all of the chat windows??

Any idea?
Cheers!
