UE5 Editor Utilty Widget : How to expose properties mentioned in details panel

Hello guys, I have created an editor utility widget that can perform adding actors, deleting, changing scale etc. functions as displayed on ss

Can anyone help me on how I can i set the opacity using blueprints to the lightcard? Also I want this to be done in editor only.
In simple words how can I expose properties like opacity, exposure, color in the editor utility widget so that I can edit the lightcard in editor?

I didn’t try these solution yet.
