ActionSheet/Sheet to Modal in SwiftUI - swift

Question

I am trying to create an actionSheet that opens a modal to save to a view. Currently, I can only get one of the buttons in the actionSheet to open to the modal. How can I rewrite the .sheet code to do this? Thanks.
#State var showActionSheet = false
#State var showAddActivityPopup = false
#State var showAddDayPopup = false
var body: some View {
Button(action: {
self.showActionSheet = true
}) {
Text("Show Action Sheet")
}
.actionSheet(isPresented: $showActionSheet, content: actionSheet)
.sheet(isPresented: $showAddDayPopup, onDismiss: {
print(self.showActionSheet)
}) {
AddDayPopup(message: "Add Day")
}
.sheet(isPresented: $showAddActivityPopup, onDismiss: {
print(self.showActionSheet)
}) {
AddActivityPopup(message: "Add Activity")
}
}
private func actionSheet() -> ActionSheet {
let button1 = ActionSheet.Button.default(Text("Add Day")) {
self.showActionSheet = false
self.showAddDayPopup = true
}
let button2 = ActionSheet.Button.default(Text("Add Activity")) {
self.showActionSheet = false
self.showAddActivityPopup = true
}
let actionSheet = ActionSheet(title: Text("What would you like to add?"),
message: nil,
buttons: [button1, button2, .cancel()])
return actionSheet
}
}
