+## Status
+
+Accepted
+
+## Context
+
+- The current implementation includes parsing the message for markdown, converting line breaks, and
+  formatting the message if necessary.
+
+## Decision
+
+- We will refactor the getEventContentFromMsgText function to improve its readability and structure.
+  The changes include:
+    1. Extracting the markdown conversion logic into a separate function.
+    2. Simplifying the line break conversion and formatting check.
+
+## Consequences
+
+- The function will be easier to read and maintain.
+- The logic for markdown conversion and line break handling will be more modular and reusable
