Unable to Navigate pages while keeping the tab bar accessible in xamarin forms

Question

So I have a tab bar and some pages attached to it, and what I'm trying to do is navigate to a different page(not a tab bar page) by clicking a button which is present in one of these tab bar pages, on doing so that page is replacing the tab bar, how would I be able to navigate inside the tab bar itself, I checked a couple of threads and doing a PushAsync should do the trick but its not working

This is a snippet of my NavigateAsync Method

  public async Task NavigateAsync(string pageKey, object[] parameter, bool animated = true)
    {
        var page = GetPage(pageKey, parameter);
        await CurrentNavigationPage.Navigation.PushAsync(page, animated);
    }

  private readonly Stack<NavigationPage> _navigationPageStack = new Stack<NavigationPage>();

    private NavigationPage CurrentNavigationPage => _navigationPageStack.Peek();

So it turns out in my navigation service, i was using the tabbedpage as a navigationpage to navigate to other pages, but if you get the current page (which should be encapsulated in a navigation while adding them as children to your tabbedpage), then using that if you navigate it creates a new page inside the current page instead of the whole tabbedpage

Here's my syntax for storing the currentPage as my navigation element to navigate

 public Page SetRootPage(string rootPageKey = null, Page pageName = null)
    {
        NavigationPage tempPage = null;
        if (rootPageKey != null)
        {
            var rootPage = GetPage(rootPageKey);
            if (rootPage is TabbedPage tabbedRootPage)
            {
                tempPage = tabbedRootPage.CurrentPage as NavigationPage;
            }
            if (tempPage == null)
            {
                CurrentNavigationPage = rootPage is NavigationPage ? (NavigationPage)rootPage : new NavigationPage(rootPage);
            }
            else 
            {
                CurrentNavigationPage = tempPage;
            }
            return CurrentNavigationPage;
            // as NavigationPage;
            //_navigationPageStack.Clear();
            //var mainPage = new NavigationPage(rootPage);
            // _navigationPageStack.Push(mainPage);
        }
        else
        {
            if (pageName is TabbedPage tabbedPage)
            {
                CurrentNavigationPage = tabbedPage.CurrentPage as NavigationPage;
            }
            else
            {
                CurrentNavigationPage = pageName as NavigationPage;                    
            }
            return CurrentNavigationPage;
        }
    }

We have a CurrentPage property in TabbedPage. You will need this CurrentPage.Navigation object to push the page inside tab bar itself.
