*No ROOT* *3rd PARTY LAUNCHER REQUIRE FOR GOOGLE*
Only say your command once to get a result from the assistant app of your choice.
Google needs to be the assistant app for it to work properly. You need to have a 3rd party launcher for Google as Google doesn't allow its voice Command activity to be started by another app.
Change the shortcut block to the assistant of your choice.
You can use this with one or more assistants and it is expandable.
Great if you have a personalised assistant but still need/want functionality of your other assistants.
