Mocks

Acceptance Criteria
Update [Required]
The user should be shown a prompt that they do not have karma points left.
@m-murad May I work on this issue? Although this kind of issue has been raised before and was closed.
I think that graying the items is not quite clear and the user should be explicitly told about the Karma points.
Please review.
I agree with @Priyansh-Kedia here. This creates a bad UX. We should add a toast or snackbar or a dialog. @m-murad @isabelcosta views?
@Priyansh-Kedia are u available to work on this issue?
Yes @HaripriyaB I am still waiting for approval
Okay assigning it to you. @Priyansh-Kedia Can u discuss what exactly is your approach for solving this?
I was thinking of showing a toast or something for the same. Still waiting for suggestions as @sammy1997 suggested.
A custom toast with a good UI would be better. @Priyansh-Kedia I think u can start working and show the mockups here so that we can decide which one is better.
