When Subscribed how to hide the bell icon in wordpress?

How to hide subscription bell after user subscribed in wordpress? Users want to unsubscribe, they can unsubscribe from their respected browsers. One signal providing this feature, here not available that feature??


You can turn off the subscription bell from your Webpushr admin console at Log In - Webpushr

I want a subscription bell it is a “mandatory” feature, but when visitors subscribe, then only the bell button needs to hide like one signal WordPress plugin. Can you please add this option to your WordPress plugin??
