Under "Setting up webhook in Zabbix", point 2 involves getting a file from the Zabbix Bitbucket, but the filename in the link is incorrect:

• Current: media_ms_teams.yaml
• Correct: media_msteams.yaml

This results in Bitbucket defaulting to an assumption that this is an access issue, prompting you to log in / sign up for a support.zabbix account, which explains #ZBX-25132. If you Google "media_ms_teams.yaml", the only results are that doc.
