How can I recover my lost developer account?

1 0 0

HI，I have created a Shopify Developer Account in 2019 with the E-mail address jiangjie@yunexpress.com. Also we published an APP on Shopify app store in the same year which called “YunExpress-shippping”. Everything went well till we didn't log in to our account for more than 3 months. We received a prompt from the web telling us that we needed to reset our password and unlock our account, but we didn't receive any emails from shopify in our mailbox. At the moment we wonder if there is any way for us to log in?
