Just click Install, then enter your username and password to allow Rosetta 2 installation to proceed. There are several ways that you can learn which of your apps need Rosetta, but regardless, your Mac will ask you if you want install Rosetta the first time you try to launch an app made for Intel. The translation layer works in the background whenever you use an app built only for Mac computers with an Intel processor, and automatically translates the app for use with Apple silicon the first time the app is run.

Rosetta 2 is the translation layer that enables a Mac with Apple silicon to use apps built for an Intel-based Mac. Macs powered by Apple silicon, such as the MacBook Pro models featuring M1, M1 Pro, and M1 Pro Max chips, can run both iOS apps and Mac apps, but they can also run x86-64 software that's been built to work on Intel architecture, thanks to something called Rosetta 2.
