do alertmanager supporting push alert to flock by webhook

[Daych Chan]

Hi there

I would like to setup the webhook from alertmanager to flock, but I can see it most related are slack_configs or webhook_configs, I had setup the incoming webhook on Flock, also updated the alertmanager.yml config, but I can't push alert message to Flock, I cant see any doc to setup the alertmanager to Flock, please help.

Below are the alertmanager.yml, it including the slack_configs is works, for the Flock's part it didnt work by using both slack_configs or webhook_configs
