Are you sure you have met any other requirements for the VCP-DCV 2023?

You don't say what other VCPs you have or which course you completed to meet the training requirement.

Check the path here which applies to you: https://www.vmware.com/learning/certification/vcp-dcv.html

The VMware vSphere 7.x (2V0-21.20) exam is associated with the Certificate VCP-DCV 2023. If you are not valid VCP Certification holder, you need join the related required training course. See on the below link detail.

If you are VCP-DCV 2022 or Newer certified, the training are just optional. 
If you are match with all requirement, you will receive a mail from certmetrics within (maybe) 72 hours after you finished the exam successfully.

You can also track all your certificates at https://www.certmetrics.com/vmware.

Hi Abhi, I was able to look up your records and confirmed the exam completion. But, as others have stated, you must also complete one of the required trainings. The order of completion does not matter, it only matters that every piece is complete.

thanks for all the details, so I need to complete vSphere 7 install, manage and administration course to get the completion of this certification ?

Any of the courses shown on the page I linked to in my initial reply:
