event reports in platform

HI all.
why not appear the event in the right column in the platform?, I means ... I see the events in the report "Events" but not in that column called "Event".
thanks.

Probably because you haven't enabled web notifications.

Hi, it is enable, I enable the traccar notification too (i don’t know what means) but not appear anything

these web notifications are not saved and are deleted immediately after the page is reloaded
