I need a little help using pinia-plugin-persistedstate.

I am trying to persist my store where I am saving files downloaded from S3
here is my store:

export const useScanStore = defineStore('scans', {
    state: () => {
      return {
        scanList: [] as ScanInfo[],
      }
    },
    getters:{
      getScan:(state) => {
        return (id: string) => {
          return state.scanList.find(scan => scan.id === id);
        }
      }
    },
    actions: {
      addScan(id: string, file: File){
        this.scanList.push({id, file})
      }
    },
    persist:true,
  })
  
  interface ScanInfo {
    id: string
    file: File
  }

After refresh, I get a hit in the store (getScan returns a Scan object). However, the file seems to be missing (I get a A Proxy with an empty target)

Any help appreciated. Thanks
