Conversion of normal hyphens to non-breaking hyphens

Hi,

I am trying to convert normal hyphens to non-breaking hyphens in Trados Studio 2022 SR2 - 17.2.10.19084. I copied the non-breaking hyphen tag from Quickinsert in the Search and Replace function, but it does not work, the hyphens remain normal. Is there another way to convert the hyphens quickly?

Thanks.
