Import existing CloudFlare resources into Terraform

I need to import existing CloudFlare WAF resource into terraform.
For that I fallow the instructions located in: Terraform Registry in my case I am trying to run:
terraform import cloudflare_access_rule.default account/<account_id>/<rule_id> .
The problem here is that I don’t know how to get the value for “rule_id”.
Will be really happy if someone give me some directions.
Thanks in advance.
