show my field column in the field part of views_ui

hi,

i have un custom column (‘my_special_col’) in the schema of my custom field plugin (FieldItemBase),

in views_UI, i can select it in the sort and filter part ,

but it doesnt appear in the fields list selector to show in the view (“my_special_col:delta” appears however).

How to show it in the fields list ?

Thx
