@Ishtiaque Ahmed CSEH Rafin Thank you for reaching out to us, As I understand you are looking for steps on how to create a Workforce tenant.
Microsoft is now limiting this functionality to only paid customers. Customers on trial subscriptions are unable to create more tenants from the Microsoft Entra admin center. Customers in this situation who need a new trial tenant can sign up for a Free Azure Account
Let me know if you have any further questions, feel free to post back.
