How to update a mutablestate uistate to set current selected item in a viewmodel? I have this uistate class, and need to change selectedBookId value.

sealed interface BooksGridUiState {
    data class Success(
        val booksList: List<BookData>,
        val selectedBookId: String?
    ) : BooksGridUiState
    object Error : BooksGridUiState
    object Loading : BooksGridUiState
}

This is the variable in the viewmodel:

val uiState: BooksGridUiState by mutableStateOf(BooksGridUiState.Loading)
        private set

Can’t do the trick of calling

.update {
    it.copy(

Because this is not a mutablestateflow, and I’m following a codelab and must use mutablestate (editado)
