works fine... but the text is always inserted at the beginning of the message. Nevertheless, into several situations, it would be useful if the inserting is made at the cursor location (as for inserting a matched civility at the end of a message, for example).

This review is for a previous version of the add-on (0.55). 

I absolutely agree - maybe I will be able to introduce this functionality (insert the text at the cursor position) in a later version of the Add-on.
Edit: The version 1.0.2 now includes the possibility to insert the text at the end of the message or at the cursor location.
