I've created a custom ToolbarContent for common buttons, such as Save, Edit, Cancel, etc...

For example:

import SwiftUI

public struct SaveToolbarItem: ToolbarContent {
    private let placement: ToolbarItemPlacement
    private let action: () -> Void

    public init(placement: ToolbarItemPlacement = .confirmationAction,
                action: @escaping () -> Void = {}) {
        self.placement = placement
        self.action = action
    }

    public var body: some ToolbarContent {
        ToolbarItem(placement: placement) {
            Button(
                "Save"
            ) {
                action()
            }
        }
    }
}

At call site:

        .toolbar {            
            SaveToolbarItem() {
                 // some code for the Action
                presentationMode.wrappedValue.dismiss()
            }
            .disabled(true) // Value of type 'SaveToolbarItem' has no member 'disabled'
        }

However, I'm getting the following error while trying to use isDisabled method:

Value of type 'SaveToolbarItem' has no member 'disabled'

How can I mitigate this error? E.g. maybe define disabled only on my custom types of ToolbarContent?
