In Rayon, changing your email is not possible, so in order to use a new email account, you'll have to create a new account and then share your models with the new account.
To manually share your model with your new account. Here are the steps:
Open an incognito tab on your browser and log in to your new account.
Click the three dots on your model and switch toggle to 'public link'
3. Copy the link and paste it into your incognito tab with the new Rayon account. You will open this model and can click 'duplicate' to your workspace.
👉🏻Repeat this process for all your rayon models.
In this case, you will create a copy of all your models, becoming their owner in the new account.
