Confirm AND exit insert mode?

[rwijtvliet]

I'm trying to create a keymap that (a) accepts the currently selected item from the list and (b) exits insert mode.

I thought this should work, but it doesn't:

          ['<C-y>'] = cmp.mapping.confirm { select = true }, --confirm and stay in insert mode: works
          ['<C-p>'] = function()  --confirm and exit insert mode: does not work
            cmp.mapping.confirm { select = true }
            vim.cmd 'stopinsert'
          end,

The editor ends up in normal mode, but the item is not selected/completed.
