Hi
@Marvin OcoAFAIK safe links does not quarantine, only safe attachments. By the policy you can block URL's, stop users clicking through to the original URL but not actually notify administrators if, for example, a link is detected.
May be worth raising a uservoice for this here
https://office365.uservoice.com/forums/289138-office-365-security-complianceThe Threat protection status report will show everything caught on safe links and you can generate reports in the Microsoft 365 security centre to send reports on a weekly basis.

Best, Chris
