Ho to know if a picture was edited ?

Hello everyone.

I moved a few months from Lightroom Classic to Lightroom CC, But I still con figure it out how to know which pictures have been edited and which doesn't.

Usually I take my time to edit all the pictures of an specific Album so is quite helpful to view in the grid view edited and unedit pictures.

There is something like that? may be a filtre?

if that feature still doesn't exist, do you have any workaround? or suggestions?

Regards.
