Eero Secure currently will tell you on which device, and what type of threat was detected (Malware, Botnet, or Phishing) but there's currently no way to see what URL/IP address/etc. was blocked, making this information of limited use.

For example, my spouse's work laptop had 22 "Malware" threats blocked, which makes me want to notify their IT department of a potential threat, but without more details that's not necessarily helpful information. For all I know it could be blocking ads on some random website for malware, but it also could be blocking something more serious. Especially in this work-from-home era, more insight into the threats Eero Secure is blocking is needed.
