+#### Mapping tool calls and responses to normal assistant - user chat flow
+
+Instead of maintaining tool_call request and resultant response in logically seperate parallel
+channel used for requesting tool_calls by the assistant and the resulstant tool role response,
+the SimpleChatTC pushes it into the normal assistant - user chat flow itself, by including the
+tool call and response as a pair of tagged request with details in the assistant block and inturn
+tagged response in the subsequent user block.
+
+This allows the GenAi/LLM to be aware of the tool calls it made as well as the responses it got,
+so that it can incorporate the results of the same in the subsequent chat / interactions.
+
+NOTE: This flow tested to be ok enough with Gemma-3N-E4B-it-Q8_0 LLM ai model for now.
+
+TODO: Need to think later, whether to continue this simple flow, or atleast use tool role wrt
+the tool call responses or even go further and have the logically seperate tool_call request
+structures also.
