Ability to show versions for external editors in Lightroom, Windows version

Watching a video from Photoshop Cafe on the new features in LR, Colin Smith demonstrates the option of picking the version of Photoshop (2023 vrs Beta) to edit in. He is using Mac. I am using Windows and the dropdown arrow only gives me version 2023. I can put the Beta version in the additional editor position but that takes away space for another program.
