How to use dynamic variables using GraphQL in NEXTjs

Question

So I am trying to build an application in which I need to pass the account as queury. How can I achieve this?

My proposed solution (which is not working obviously):

let account = '0x74c7b157af4E5418F03eb928DF309cc98CE38E66';  
const GET_ACTIVE_ITEM = gql` 
{
   activeFiles(
      first: 5 
      where: {Account_contains: ${account}}
    ) {
       id
       tokenId
       ipfsHash
       Account
       Privilege
      }
}`

Error message I got
