Office JS Outlook and update email body when composing a form

Question

I would like to know if with Office JS Outlook addin, is it possible to set email body automatically when opening and composing an email.

I have already succeed to do it using addin commands and MessageComposeCommandSurface extension point element in the manifest.

However, my code is execution only after a click on a button in the ribbon.

Is it possible to execute my code automatically when the compose form is loading instead of having to click in a button to execute it?

Thanks a lot
