@Raunak Basnet Thanks for posting in our Q&A.
From the second screenshot you provided, it seems that you didn't enable automatic MDM enrollment. To clarify this issue, we appreciate your help to collect some information:
1.Please make sure you have Microsoft Entra ID Premium subscription and intune license.
2.Then you can set up automatic enrollment.
3.Please check if the MDM authority shows "Microsoft intune" under Tenant admin > Tenant details in intune portal.
If above steps are finished, you can try to add your work account (which has an intune license) under Settings > Accounts > Access work or school. This device will be enrolled to intune.
Hope it will help.
