Android: Open custom webview url when tap on notification

I have a working webview/hybrid Android app, everything is already set and working good with no errors or issues. Currently using Android Studio 3.6.3. I'm using Firebase Service Messaging along with PHP script via CURL to create and send notifications to device. They work good, they receive the title, body, sound, and URL strings and they are being displayed correctly in device. Now I just want that this URL I'm passing via PHP opens inside the webview app when the user taps on the notification. Currently, if user taps on the notification, it opens the app in the home or default URL of the app. MainActivy, AndroidManifest, MainFragment, and all java files are ready and working with no issues. I just need to know what to add, edit, or change to accomplish the task just mentioned. I can share files mentioned if needed. If you know how to achieve this successfully, just let me know. I already tried several ways creating the intent in the FirebaseMessagingService file but not sure how to make it work or connect it with the MainActivy or Fragment file so it opens the url. If the job is done successfully by an Android developer with experience in this matter, I could rehire to set up deep/app links too, which I'm also interested in making them work. Forgot to mention. Would like to hire someone who can solve it today if possible. Just let me know how much it would cost. Not sure about it.
