unable to build chain to self-signed root for signer Apple Developer XXXX

I have recently been added as an apple developer in an organization by our main developer.

On my mac, within keychain access, I have two certificates, one under my name and one under the company name. Both are not trusted. I am not sure what steps I need to perform to get those certificates to be trusted.

I suspect that maybe my account does not have the privileges required regarding generating trusted certificates despite me being a developer in the organization.

I get the error mentioned in the title when trying to deploy my app on a real device for testing which I am convinced is tied to the fact that my certificates on my target machine are not trusted.

All the solutions that I have read online have failed me and its quite impossible for me to proceed forward at this point without any assistance.
