If you’re already signed in with a personal account:
Go to Settings
Start > Settings > Accounts > Access work or school
Click “Connect”
Select “Add a work or school account”
Enter your work email
This should be the Microsoft Entra ID (Azure AD) or Microsoft 365 account provided by your organization.
Don't sign into your work email yet. Instead, click on "Join this device to Microsoft Entra ID". On the next step, you will be prompted to sign in, then you can sign in using the work email. Once done, restart the computer and you can use "switch user" to sign in using the company email.

Do you want this computer as only work or business? so don't want personal account on it? Have you got Pro or home edition of Windows on the laptop?
If this was missing you might have home edition, in search type winver and open that app, that will tell you.
