Why are instagram links opening in wrbview?

Question

Java

Greetings. I made a simple application on webview and in it third-party links (including instagram) should, in theory, open outside of my application. It seems to work with all sorts of VK, vatsap, facebook, email, etc., but with instagram links some miracles and only instagram pages open inside my webview. Here is what I did:

if (_url.startsWith("https://instagram")) {
          Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("_url"));
          startActivity(browserIntent);
        }

I've tried everything, it just doesn't work.
What did I do wrong, please tell me.
