Private Members Dataset

Quick question. I have used the wix members area on Studio to register new members. This saves members data in the Private Members Dataset. I have used all 4 of my emails to test my site and I wish to clear my data from this collection so I can continue testing. It appears I can’t manually remove members and therefor I can’t continue testing my entire process. What advice would you have for me about testing my site without using this collection or what can I do to remove myself from this dataset? What should I do if I wish to have more control over member data but still wish to.
