I just wrote it. If you mean, can I find a source saying that it's only a possibility, no, more-or-less by definition.
The WHO scientific briefing on transmission says "Therefore, transmission of the COVID-19 virus can occur by direct contact with infected people and indirect contact with surfaces in the immediate environment or with objects used on the infected person (e.g., stethoscope or thermometer)." but it's not at all clear whether that applies to supermarket shopping trolleys and so on. There certainly doesn't seem to be any suggestion that it spreads directly through skin contact, though picking your nose after shaking hands with an infected person who has just sneezed onto their hand is not a good idea at all.
Of course absence of evidence is not evidence of absence, and a degree of caution is sensible, but so is a degree of realism.
The bit that you quote suggests precisely, albeit not expressly, that supermarket trolleys are exactly the kind of thing that can transmit the virus. You don't get it directly by touching the trolley, you get it on your skin. If you then touch your nose, mouth, eyes, before washing your hands, or sanitising them, the virus is in.
There is some discussion as to how long the virus can live on a variety of surfaces, but it seems to be measured in hours and days, and not in minutes and seconds.
Given that the trolley that I return with virus on the handle is the next one to be taken by the next customer, there is not going to be hours between consecutive uses.
