SAP datasphere free tier - no free plan

Hello,

I registered for a free Pay-As-You-Go for SAP BTP in order to request a SAP Datasphere free tier tenant.

I followed the tutorial https://developers.sap.com/tutorials/data-warehouse-cloud-1-begin-trial.html .

In the SAP BTP, I created a sub-account by selecting Europe and AWS. In the sub-account, when I click on the button "Enable cloud foundry", I don't have the possibility to choose free plan as shown in the above tutorial.

Is the above tutorial not updated ? Is it not possible anymore to request for a SAP Datasphere free tier tenant ? What is the process to enable it ?
