customIdentityProvider() { const baseAPI = '' //////what is this value???? const userId = '30317220-c72d-11ed-2137-0242ac120002'

            const getToken = async () => {
              const response = await fetch(`${baseAPI}/getToken/${userId}`)

              const token = await response.json()
              console.log('getToken', token)
              return token
            }

            const getFreshToken = async () => {
              const response = await fetch(`${baseAPI}/getFreshToken/${userId}`)

              const token = await response.json()
              console.log('getFreshToken, token')
