Where to change account email for extensions.gnome.org?

Hello,

Can someone help me about changing email address of my account at extensions.gnome.org?

I registered the account with my old email address a long time ago. Now I
would like to change that email to a new one, but I can not find any
settings about it on the website. Do you have ideas?

Thank you!

Greetings,
K.K.
