Would this be a good addition:

-    def get_notes(self, default_empty_value: Optional[str] = "") -> List[List[str]]:
+    def get_notes(
+        self, default_empty_value: Optional[str] = "", range: Optional[str] = None
+    ) -> List[List[str]]:

# ...

         params: ParamsType = {"fields": "sheets.data.rowData.values.note"}
+        if range is not None:
+            params["ranges"] = absolute_range_name(self.title, range)
         res = self.client.spreadsheets_get(self.spreadsheet_id, params)

@lavigne958 I have added tested the code and it works as expected.

Should I open a pull request?

hi hi @muddi900! thanks for the enthusiasm :)

we'd love to have a PR! it would be great if you created a unit test to test the new functionality, as we try to create for all changes.

if you need some help with the testing framework beyond the contributing guide, let us know and we will be happy to help :)
