Hello! ATM i'm use Zabbix 7.0.13 and faced with problem: macro is not resolves in webhook parameter value, like described in https://www.zabbix.com/documentation/current/en/manual/appendix/macros/supported_by_location_user#other-locations 

Steps to reproduce:

1. Create global macro like '{$MYMACRO}' = 'test'
2. Create simple webhook with parameter which include this macro and has simple script like this:

var params = JSON.parse(value);
console.log('INIT: ' + JSON.stringify(params)); 

Result:

00:00:00.000 [Debug] INIT: {"parameter":"{$MYMACRO}"} 

Expected:

00:00:00.000 [Debug] INIT: {"parameter":"test"}
