How to insert the currently logged in user into the word template.

Hi,

Does anyone know or have any idea on how to retrieve the name of the currently logged in user and dynamically insert it into a word template in online crm 2016?  What I want to achieve is that when a user generates a word document from within online crm 2016 his/her name will be automatically inserted into the generated word document.

Thanks,

Dzung.
