How will the robot of Yandex and Google like it if I generate sitemaps every time, regardless of changes?

Question

Create a sitemap

I'm going to use spatie sitemaps to generate sitemaps in the stall. The simplest use case involves a full site scan and the output is a sitepam file. So, in order not to be smart, I think to run this scan twice a day, thus I will always have a fresh sitemap. The sitemap has a modification date for each page, with this approach, all dates will be constantly updated, regardless of whether there were changes on the pages or not. Question: How do robots feel about this ?, is this not regarded as an obsessive attempt to re-index the page without changes, or is it better not to do this?
