If a cooking pot was expressly intentionally toveled in a kosher mikva by someone who is not religious (intentionally does not keep shabbat, kosher etc.) and did not make a blessing, but followed all other requirements (eg. removed labels) is the pot considered toveled? The fact that the item was toveled can be independently corroborated (3rd party or video camera etc.)
