How do I add a growl to an audio file of me speaking?

Question

I'm trying to use Audacity to make a "voice of God" sound with an audio file of me reading some sentence. I've already added the following effects:

Echo

Delay time (seconds): 0.25
Decay factor: 0.5

Pitch

Pitch: F9 (11025 Hz)
High quality stretching: On

Reverb

Room size (%): 100
Pre-delay (ms): 10
Reverberance (%): 100
Damping (%): 100
Tone Low (%): 100
Tone High (%): 100
Wet Gain (dB): -1
Dry Gain (dB): -1
Stereo Width (%): 0

Is there a way to add a low growl when some of the words are said?

Side note - if you have any other ideas to make this sound more powerful and scary, I'm all ears!!!

Well I would suggest using a VST plugin if you're familiar with that. I wrote down the ones I'm using for you with links:

RoVee

Clownfish Voice Changer

Graillon 2 Live Voice Changer

MAutoPitch

GForm

Pitchproof

KeroVee

I Hope this can be of any help for you, even though I'm 11 days late to see your question. :D
