How to solve the problem with pageview and Product Impressions?

Question

Google

Data about Measuring Product Impressions, Measuring Views of Product Details is passed to GA after the call . ', 'pageview'); `. It would seem that you can just call `ga('send', 'pageview'); `, but this may affect the metric, because in fact the page is still displayed on no one has crossed it, so passing the Track Type as a pageview is incorrect. Does anyone understand the pain? Has anyone solved this somehow? Many thanks in advance to everyone!
