Is it necessary to sort posts in sitemap.xml?

Question

Google

My boss says that the entries in the sitemap.xml file should be sorted in order of importance and update date.
I quote:

The robot scans the page from top to bottom in a row.
The more important a page is to us, the higher it should be. Similarly, with the update in that situation.
Of course, there are not many of them here, but still the robot does not run through the entire site at a time, so it is also important that we give it to it in the first place

I fundamentally disagree with this. Because I upload the update dates to the file. And as for the importance of the page, there is a priority field for this. Correct me if I'm wrong.
