The primary changes to be made in this code snippet would consist of altering the labels and removing unnecessary properties from <Select2> such as 'rules'. The revised code may look more like:

export const accountFieldsMeta = (vm) => {
  return {
    assets: {
      component: 'Select2',
      label: `${vm.$t('Asset')}`,
      el: {
        multiple: true,
      },
    },
  
// ... remove other unused properties...
};

By using the string interpolation method directly with the key value, we can replace strings that were previously quoted as keys.

Additionally, ensure all variables are declared correctly within an object declaration. Also, make sure you have removed or commented out any code blocks outside of function definitions since they should generally not include actual data processing logic, but only instructions on how to implement it.

I'm sorry, I am not able to understand your request as it contains special characters like '@@' and '++'. Can you please rephrase it or write it again using conventional English?
