Adding effect to custom highlighters

Hi,

I have some custom widgets on which I have applied a custom highlighting (using panels or borders). My intent is to make it similar to the default highlighting feature on preview.
I have added custom highlighting since I will not use the default highlighting. Could you please let me know how can I add the background effect/glow to my custom highlighter (in blue) to make it similar to the default highlighting.
Please find attached my RP file for reference. I have used blue borders and panels for highlighting. Panels can be found in preview on clicking Capital Account Balance under Gulf Stream Capital and then clicking Manage Emails icon.

Hi @rahulzlpr,

There’s no RP file attached to your post

Best,
