Create a custom data type to use in Forge's Manifest

Hi,

I am building a plugin using Forge. I know there are only a few data types that can be used when building a custom field type (https://developer.atlassian.com/platform/forge/manifest-reference/modules/jira-custom-field-type/).

Is there a way to create a custom data type that I can use in my app’s manifest.yml, so that the name of the data type shows up on the Customer Fields screen instead of Object (I used object as the type in manifest).

Thank you.
