Let ConfirmBehavior.Insert insert the same as cmp.ConfirmBehavior.Insert

[GordianDziwis]

In this example, print!(...) was selected, but only print! was inserted.

What I want to achieve is that the ghost text () is inserted as actual text.

Here is my related config:

        ['<cr>'] = cmp.mapping(function(fallback)
            if cmp.visible() then
                cmp.confirm
                    { select = false, behavior = cmp.ConfirmBehavior.Insert };
            end;
            fallback();
        end),
        -- ['<space>'] = confirm_mapping,
        ['<Tab>'] = cmp.mapping(function(fallback)
            if cmp.visible() then
                cmp.select_next_item { behavior = cmp.SelectBehavior.Insert };
            else
                fallback();
            end;
        end),

Does anyone have some hints?
