Regex Validation for Workflow

[muhammetayal]

Hi everyone, 

I want to write a regex code and it should show me only below sentence 

My sentence: ABCD-1234: Muhammet Ayal Test

should be result: "Muhammet Ayal Test"

Thanks for now

\s(.+) , but this will also give you the space after ':'

the above regex takes everything after the space including the space.
