Ok, that’s good news. 
Did you read the first FAQ yet on using edge? All drivers are added in the same way. See D. And E. In the FAQ.
FAQ: I have no idea what Edge is. Is that a new developer tool? (2022)
You will just follow a link that you will get from the forum thread about the edge Driver, subscribe your hub, then select the specific edge driver you want downloaded.
Here is the link to Mariano’s channel. (It’s in the community thread, but it is kind of hard to find.)
Once it has been downloaded, you should be able to change to it in the smartthings app.
Sometimes it works better If you delete the device from your account, download the custom edge driver, and then, when you add the device back to your account, it should automatically pick that driver as long as there is a fingerprint match.
