I get confused while setting modifiers for different composable functions if i create a composable function that function create a whole ui as of now since o have made only basic apps which contains for eg image text or icons etc so i used a fill max size() modifier function now where should i pass it should i pass it in the function where i am previewing and calling the function which comtains the ui or should i write it in the row or column parent composable in the function that contains the ui coz just sometimes for eg if it is a column composable only first element of the column is visible and just takes the entire screen
