UserVisibleHint is deprecated
In androidX UserVisibleHint is deprecated. I guess it would be good to move away from using it.

According to [this stack overflow answer](https://stackoverflow.com/a/57886213/16386923) the equivalent would be:

For UserVisibleHint = false
```
.getSupportFragmentManager()
            .beginTransaction()
            .setMaxLifecycle(fragment, Lifecycle.State.STARTED);
```
For UserVisibleHint = true
```
.getSupportFragmentManager()
            .beginTransaction()
            .setMaxLifecycle(fragment, Lifecycle.State.RESUMED);
```
