How to set RAM when calling an Actor via API (Python client)?

Hi,
I’m running the novi/fast-tiktok-api Actor from my Python app using the Apify Python Client.

Here is a simplified version of my code:

from apify_client import ApifyClient

client = ApifyClient("APIFY_TOKEN")

run_input = {
"limit": 10,
"region": "JP",
"type": "TREND"
}

run = client.actor("novi/fast-tiktok-api").call(
run_input=run_input
)

I would like to set the RAM (memory) for the Actor run, for example 128 MB or 256 MB.
I tried passing memory=128 directly to .call(), but I got the error:

ActorClient.call() got an unexpected keyword argument 'memory'

Could you please show me the correct way to configure RAM (memory) when calling an Actor from the Python client?

Thanks a lot!

First result from Google explicitly says:
You can set the memory for a given Actor run by using the optional named argument memory_mbytes in the call() method. So, for example, you can run Actor with 8GB of RAM by calling client.actor("aYG0l9s7dbB7j3gbS").call(run_input=run_input, memory_mbytes=8192) ...
