Window size and Position

How can I control the Writer window size and position? I want to quickly open a new blank Writer document with the windows set to a small very narrow size, positioned at the side of the computer monitor screen, with View= Web, so that the text words will wrap to fit inside the window.

Use case: taking notes during webinar. Webinar needs most of the computer screen, therefore LibreOffice Writer document window must be small and positioned near edge of screen.

Is there a way to set window size and position from a saved LO template?
Alternately, are there any commands that could be used to automate the procedure of positioning the window?

Thanks!
LibreOffice v6 on Mac OS 10.14 Mojave, also Keyboard Maestro macros can be used if helpful.

The window size and its position on the screen is not controlled by LibreOffice but your desktop manager.
