Is it possible to switch & control two Android apps with Appium?

Use Appium Desktop ver 1.10.0 and

org.seleniumhq.selenium
selenium-java
3.13.0


io.appium
java-client
6.1.0


org.testng
testng
6.1.1

I want to, switch to the 2nd Android native app, copy a message, switch back to the 1st native app and paste the message.
My 1st question is if this is possible?
If yes, my current problem is, I can switch to the 2nd app by
driver.activateApp(appPackage);
but I have no control on the 2nd app.
