WinUI3 : How to build a tokenized text input

Hi,

I'm building a desktop app using WinUI 3 in C++/WinRT (no XAML, code-only approach), and I'm trying to create a text input experience where users can type words, and once they hit space or Enter, that word turns into a token or "chip."

Think of it like the chat input in Microsoft Teams, where a selected name or mention becomes a visually distinct token that behaves like a single, atomic unit. For example, the token can’t be partially edited. When the user presses Backspace, the entire token is removed in one go.

Is there any native support in WinUI 3 for this kind of behavior? Or would this require building a custom solution to get the desired experience?
