How can I filter Windows 10/11 notifications based on string/regex?

I’m looking for a way to filter Windows 10/11 notifications based on their content, be it string match or even regex.

My current use case is that I’m in a Discord server which has a “firehose” channel which sends out a ton of messages for which I get notifications. Discord itself has no way to filter notifications based on their content, and the way this Discord server is setup it’s either all or nothing. I care about only messages containing a few specific strings. Everything I don’t care about and want to filter them out.

Ultimately, I’m looking for something that can pattern match my string/regex to display(or hide/dismiss) notifications. This can be useful not just for Discord but other apps too.
