I have applied the changes please review it .

Thanks for the patch @niharika.s

Can you check if there are other components in the same case ?

Also after that, can you provide a Merge Request ?

I've made the changes on my side and applied them in the MR. Let me know if you need any further adjustments or if there's anything else you'd like me to address.
