How do I upload a body with hair? "The following optional accessories were not found"

[VEGA_0G (Sayuri)]

Hi everyone,
Pls Help! im trying to upload a body to Roblox, but it is not detecting the additional hair:

both the hair and the body are ready to be uploaded to Roblox separately

I tried to look for information everywhere, I’m supposed to be able to upload a body with optional accessories like hair, but there’s no explanation of how to do this exactly.

I found this image that shows how that screen should look:

Publish to Marketplace | Documentation - Roblox Creator Hub

Am I doing something wrong?
Do I have to upload the hair first and then sell it along with the body in some way?
How do I upload a bundle like this?

The accessory must be named “HairAccessory”

Yes, I finally found the solution ^^
