TRC20 curl for getaccount/getbalance

Question

What is the correct curl format to view trc20 balance of an account? I tried the below command, but the output showed no balance.

curl -X POST http://127.0.0.1:8090/wallet/triggersmartcontract -d 
'{
"contract_address":"TCFLL5dx5ZJdKnWuesXxi1VPwjLVmWZZy9", 
"address":"TUT5SVvKmnxKpKdHi2tXMzPfffQNg7e3MU", 
"function_selector":"balanceOf(address)", 
"owner_address":"TUT5SVvKmnxKpKdHi2tXMzPfffQNg7e3MU", 
"visible":true
}'

output:

   ]
}

I use the default main_net_config with supportConstant = true. Do I have to enable anything else in my config file?
