@ParimalDubewar Sorry to hear you're facing problems. Unfortunately the information you provided is not sufficient for us to be able to help.
What do you mean by "not working at all", what is it expected to look like and what do you see instead?
Which exact spine-unity version are you using (name of the unitypackage, also listed in Assets/Spine/version.txt, or the version in the Unity Package Manager window if installed this way)?
Which component are you using? SkeletonAnimation, or SkeletonGraphic?
What are your component settings, including the Advanced section (share screenshots)?
Do you see the Blend Mode Materials properly populated in the SkeletonDataAsset, as described here in the documentation:

In general please provide as much information up front, this saves both sides a lot of time.
