Unable to codesign (error: CSSMERR_TP_NOT_TRUSTED)

I am trying to configure macOs image from shared runner to be able to build our iOS app.

  image: macos-11-xcode-12
  tags:
    - shared-macos-amd64

For this I have done following things to codesign my app:

  1. Created Keychain
  2. Unlocked Keychain
  3. Imported Root CA and Apple WWDR Certificate
  4. Imported Private Key
  5. Imported Distribution Certificate

But still when I list codesigning identity, it does not show up in valid list. It shows the identity in matched identity with error CSSMERR_TP_NOT_TRUSTED :

... previous steps before this command are executed
security find-identity ~/Library/Keychains/MyKeychain
250 Policy: X.509 Basic
251   Matching identities
252   1) AXXXXXXXXXXXXXXXXXXXXXXXX9 "Apple Distribution: Company Name Here ([MASKED])" (CSSMERR_TP_NOT_TRUSTED)
253      1 identities found
254   Valid identities only
255      0 valid identities found

I am not being able to codesign my app because of this error. How can I solve it? I tried everything from this link also.

Here is the output when listing private key and certificates:
