How to get the markup string of rich object instead of printing them on the console?

[2catycm]

For example, we may have a RichTree object

root = Tree("🌲 [b green]Rich Tree", highlight=True, hide_root=True)

    node = root.add(":file_folder: Renderables", guide_style="red")
    simple_node = node.add(":file_folder: [bold yellow]Atomic", guide_style="uu green")
    simple_node.add(Group("📄 Syntax", syntax))
    simple_node.add(Group("📄 Markdown", Panel(markdown, border_style="green")))

Now, it is certained that we can print the object on the console by console = Console(); console.print(root) .
But that's not what I want, I want to find somekind of to_string method of Tree, I want to know the markup of colors and other formats of root.
I want to see the str like "[bold green]Processing[/bold green]" with "[bold green]".
Once I have the string markup, I can do automatic processing on that.
