Automation for threat weights that are "High" or "Critical." on Fortigate to a webhook

I want to send data to a SOC. The SOC is using LimaCharlie and they can receive alerts with webhook.

On my Fortigate I want to create a trigger for all threats that have the weight "High" or "Critical.

I am here:

Security Fabric > Automation > Create new

* Name: LC High/Critical Threat

* Description: Send threats to LimaCharlie over webhook

Now when I click "Select Entries" + "Create" I get the following:

Where should I continue in order to find the threats?

The webhook URL is 

b76093c3662d5b4f.hook.limacharlie.io/ORGID/ADAPTER_NAME/PASSWORD
