Hello, @Rohit_,
Thanks for the access and the slider revolution editor URL I have a login and check your issue. I try to insert the custom SVG icon in the layer but whenever I try to insert it says to try the premium version and on your site, the basic version of the plugin is installed because with the theme it comes not the PRO version. I made a video of the testing I made here is the link to the video https://streamable.com/ggjj2m I hope you can understand.
