I'm receiving the duplicated message in MS Teams.

[Yoori.H]

- Zabbix version: v6.0.0

Hello. We configured to receive Zabbix notifications in MS Teams.
We're receiving the notifications well, but the notifications is always duplicated.



I found the same issue on the Zabbix Forum page.

https://support.zabbix.com/browse/ZBX-22160

I modified the script according to the content of this site, but the issue was the same.
Our zabbix version is 6.0.0 and I changed this part.



Does anyone know a way to solve it?
I shared AS-IS / TO-BE script though.
