Mobile testing concurrent with Web testing in UFT - Tools option?

We have designed few functional automation scripts using UFT for our Web and AS400 applications. Now we are planning to add mobile testing to our test suite for E2E testing. Below is a sample test case.

Test steps:

Step 1: Login to the web application/AS400 and do some changes(This triggers a notification in mobile app)

Step 2: Open the mobile app and validate if the notification is popping up in the app. If yes click on a link in the app.

Step 3: Check on the Web browser/AS400 if the notification is accepted from the mobile device

Guidance needed for below items considering above steps:

1. Can UFT be leveraged for Mobile automation without additional license. Currently we have UFT 14.

2. Do we need Mobile center to do mobile automation

3. Can we integrate with any opensource tools like Appium directly without Mobile center. If yes will the test work for above concurrent steps.

4. How can i find the other Mobile testing tools which go along with UFT
