Cannot select between apps with the same name

I have a Samsung Galaxy Note 8 (N950U) that comes with a pre-installed photos app called "Gallery" (package name: com.sec.android.gallery3d). The phone is not rooted, and the pre-installed app cannot be disabled or uninstalled.

My preferred photos app is a third-party app that also calls itself "Gallery" (package name: com.simplemobiletools.gallery.pro). Running "launch -l" shows both apps, both named "Gallery", but running "launch Gallery" or "launch gallery" only opens the pre-installed app.

I tried running "launch com.simplemobiletools.gallery.pro" directly, but it returned "unknown command".

Is there a way to choose which of the "Gallery" apps to open?
