re-map zoho / Help desk

re-map zoho / Help desk

I tried to re-map zoho support to my website domain but must have got something wrong.

Now everytime I click the zoho support it takes me to a dead page on my domain and I can't get back into zoho support to change the settings.

Does anyone know how to get back to the original zoho support if a wrong redirect has been entered in the mapping setting?

Where can we find the URL for my Zoho desk?
