Distinction of Google Discover sources
Google has announced changes regarding the detection of their traffic sources: https://developers.google.com/search/blog/2021/02/search-console-performance-discover-chrome
In the past, we received the information discover.google or googleapis.com/, now it is no longer communicated by Google. This source is therefore transferred to "Search Engine / Search".
As we are dependent on the information shared by Google, we can no longer identify the traffic coming from Suggestion Chrome.
