No option for text replacement

[pajew]

I can see ignore and require rules but can't find menu for replace text definition.

It's at Text-To-Speech -> TTS Text Replacement.

The main screen is mostly for options that determine whether a notification should be spoken, with a few exceptions.
The TTS screen is for options related to how notifications are spoken.

Sorry if it's not the most intuitive. UI/UX design is not my strong suit and for the most part I design it for myself.
