How can I verify that it was WIndows Defender that asked me to allow sending a file about Brave update?

I am using Windows 11 Home on my pc. Yesterday, some time after updating Brave browser, Windows Defender asked me to allow a file to be sent. The name of the file had something like the words 'brave' and 'update' so I allowed it. Now I think this was the first time I had this event and I am curious if it was authentic and I want to know if I can verify the authenticity or can get an update about the file that was probably been sent to be checked. I also use a laptop with Windows 11 Pro installed and also updated that Brave browser at the same and it didn't asked me to allow for a file to be sent.
