Pulsating tone?

Is it possible to create a pulsating tone in audacity?

Windows 7
Audacity 2.3.2

Select a region of an audio track where you want the pulsating tone,
then apply this code in the “Nyquist Prompt” effect (https://manual.audacityteam.org/man/nyquist_prompt.html)

(mult 0.8 (hzosc 2) (hzosc 440))

Thanks again!
