Comprehensive Guide to DLP Policy Tips

HI. I'm trying to create a DLP policy which shows custom policy tips in multi language. The use case I've here is to create a DLP policy to identify the emails which are sent outside the organization (to some specific recipient domains) and to detect if it contains some sensitive content or if the email contains password protected attachment. I'm looking to implement policy tips in multi language along with override option.

I've tried to implement this approach using Powershell based translation approach (a combination of DLP policy and some couple of PowerShell commands) as per this Microsoft link - https://learn.microsoft.com/en-us/purview/dlp-ol365-win32-policy-tips#powershell. The problem here is - it is working in outlook web but not working on outlook desktop. I understand that the cutom policy tip has some limitations to make it work in outlook desktop but is there any other where i can make it work in both outlook desktop and outlook web please?
