When a data model becomes inaccessible (e.g., due to data corruption), the data model "Delete" command on the GUI is greyed out. This prevents the creation of a new data model with the same name, when there are no usable backups that can be restored.
Currently, the only option for Board Cloud users is to create a Support case to the Board Cloud team, asking for the data model folder to be physically deleted from the file system.
It would be useful to have the data model "Delete" command available (not greyed out) even in case the data model is not accessible, in the same way as for an healthy data model.
