Yes, you can easily trigger the signer by using the standard nostrconnect:// uri scheme. That's what a "Login with Nostr" button should do. We even added support for a convenient "callback" parameter, so Primal will redirect back to your app immediately after establishing the remote connection. If it's a browser app, simply use callback=https://[your_app_login_progress_page] to get redirected back to your app. @Derek Ross implemented this flow for some of his web apps; it works great. Derek, maybe you could share a quick video of this in action?
