+to store it.  Double clicking on the application will run it.  Since the

+    https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac

+2) Select "Open" in the menu that comes up.
+3) That will bring up a confirmation dialog about allowing the application to
+   open on the system.
+4) If your account does not have administrator privileges, there'll be an
+   additional dialog asking you to authenticate as an administrator to apply
+   the exception to the security settings.
