Regex trim help in Azure Data Explorer

Question

Hello,

I have a Azure Data Explorer query that returns ID as part of it.
The part of the query is like that:

id = any_id,

Since I'm using this ID as a placeholder in an automation process, I nee to strip the ID from anything but numbers or letters.
Trying to do so with regex failed although I was working according to the documentation below:
https://learn.microsoft.com/en-us/azure/data-explorer/kusto/query/trimfunction

The line in the query looks like that:
id = trim(@"[^\w]+",any_id),

Unfortunately the data still comes with characters that are not only letters or numbers.

Assistance will be greatly appreciated :)

Thanks!
