How To Enable Result Preview in Sly?

[daninus14]

Hi, when doing M-. with slime, if there are multiple options, like when there is a generic function and methods implemented, if I have the cursor over one of the results in the results buffer, the other buffer (If I split the screen vertically) will automatically show a preview of the file with the result focused, and when I move the cursor in the results buffer to another result, the other buffer will show a preview of the file without actually opening it permanently in my opened buffers list.

Is there a way to enable this in sly?
