How can I add multiple authors to a plugin?

I can see that this plugin, for example, has 2 authors: Base Styles | Figma Community.

However, after searching around the issue for a long time, I can’t work out how to do this for the plugins I am developing!

Can anyone help?

You can add plugin contributors when publishing/updating a plugin, as well as when editing the page of a published plugin.

Thank you. Perhaps this feature is only available for Community plugins? In my private plugins, the field is un-editable:

Unfortunately, I can’t help on this issue because I didn’t develop private plugins/widgets. And this is not described in the articles of the Help Center.
