I would say you want to return the part if you can. Usually to do a glass only repair you have to have special equipment since you have to separate the old glass then re-adhesive the new glass to the old LCD and make sure you don’t have any defects or get anything trapped under the glass when doing it.
I have never done a glass only repair but I hear it’s something that takes some skill. We always but the full assembly when it’s a fused LCD model like this.
