Getting 'This certificate is signed by an unknown authority'

We are integrating Airship for web push notifications and followed the instructions at https://support.airship.com/hc/en-us/articles/360017992631 and to generate .p12 certificate we followed the below instructions

  1. Created a CSR as specified in https://help.apple.com/developer-account/#/devbfa00fef7
  2. Uploaded CSR to down certificate on dashboard.
  3. Downloaded the certificate and double clicked to add to key chain.
  4. We got this error. ('This certificate is signed by an unknown authority')

Can you please help if we are missing anything here. Thanks in advance.
