Can this pull Alerts?

[21020620]

Hi team,
This is just a minor questions, mainly because I am not so sure about what this repo does. However, I am using Trellix and I have a main activity feed where I can see the alerts from all the hosts I manage.
I wonder if I can use this code to pull alerts, and if it can, I would like to send it to Splunk

So I used the samples.splunk argument, and I did uncomment the code part for the any_case_event function.
Butsince I ran the command:

mvision-edr-activity-feed --url https://api.soc.ap-south-1.trellix.com/ --client_id YOUR_CLIENT_ID --client_secret YOUR_CLIENT_SECRET --module samples.splunk --loglevel=debug

I have never received anything, all were empty brackets Received payloads: [], just like the example image in the repo's README file.

I think I have mistaken the command, can someone help with this question please!
