Need help in removing information on some threads

I accidentally posted a public question, thinking I was submitting it to a Jotform representative. Our invoice is also attached to that question, which is not public for everyone to view. I've googled how to remove it, but I'm not seeing any kind of "edit" or "delete" options on my account. I need assistance with removing this ASAP. 

Hi Adrienne,

Thanks for reaching out to Jotform Support. You can share the thread link where you posted the information so we can further check it and help you delete the information that you accidentally shared.

Once we hear back from you, we'll be able to help you with this.
