REGEX - Replace numbers with an asterisk, multiple apperances

[KMoryson]

Hi, I am trying to find a way to replace numbers in strings with an asterisk, if they are concatenated with one, and if not then also with one, using rex field, example:

AA-1234-12-A
BB-1-132-B-1
56-CC-1-345

to be replaced with:

AA-*-*-A
BB-*-*-B-*
*-CC-*-*

I tried multiple sed commands from the internet but they either don't work properly in splunk or do not solve my issue in the exact.

Many thanks

Does something like this work for you?

| rex mode=sed "s/\d+/*/g"
