How can I use the iPhone's keyboard within iPhone Mirroring on my computer?

I sometimes want to run the iPhone Duolingo app via iPhone Mirroring on my MacBook Pro (MBP). However, I can find no way to make the iOS keyboard that would normally appear if I were running the app directly on my phone appear within iPhone Mirroring. **Is it possible to make the native iOS onscreen keyboard appear in this scenario?** The only workaround I can find for entering forwign text is to open up a separate text editor on my MBP, use one of the MBP's keyboards to produce the desired text, and then copy-paste into the iPhone Mirroring app. Aside from the extra steps required, the iOS keyboard for a foreign language is often much cleaner to use than any of the keyboards available in macOS.
