Remove / strip HTML tags from input via Feedreader

I have finally got Feedreader to send updates via Telegram once there are new RSS entries. However for one feed it also sends the HTML tags such as < p>, <br/ > and so forth. I have been searching for a way to filter or remove these tags and I think it might be possible using some sort of template/regex string replace code, however I have no clue on how to actually code this. Any hints/guidance are most welcome!

The automation uses text_input helpers according to the video instructions at Feedreader

Below is the actual Telegram message in the automation. It’s this trigger {{}} that includes the HTML tags.

service: notify.external_warnings
  message: |-

This one worked for me but not used it in a while

{{ | striptags }}

That did the trick, awesome!!! Many thanks!
