How to make Push Notifications (Notifications) by keywords in the Angular + Ionic development environment?

Question

Angular

I set out to embed notifications in the application if the user himself selects a filter or keywords for which a notification is sent that this material containing the keywords has appeared on the site and can be read right now. But alas, it is not clear where to look for information on this topic (namely push notifications with keywords filter )

Have you looked at PushWoosh? There is an option to send notifications with the tag docs.pushwoosh.com/docs/settags
