How to remember state in screen after navigation with Kotlin?

I$$m making an app in Android Studio using Kotlin$/$Jetpack Compose.

The basics are:

$*$ In the Home Screen, the user can click on a district $($District being an enum class$)$ from a dropdown menu, and choose to see the number of votes for each political party from that district.

$*$ From the Home Screen, the user can also navigate to a Party Screen by clicking on a Card for a certain political party. This will take them to a Party Screen, where they can read info about that party.

$*$ From the Party Screen, the user can navigate back to Home Screen.

When the user navigates back to Home Screen, I want the Home Screen to remember which district the user chose before navigating to Party Screen, so that we still display the votes from that district. However, I$$m not sure how to do this.

Home Screen and Party Screen use different ViewModels, so I$$m not sure state hoisting would help here.
