Cant assign Organization Policy Administrator role to myself

[oteiza-a]

I am the sole owner of the organization, yet when i wanted to modify a policy, it says that i don't have the permission:

I researched and noted that the Organization Policy Administrator role has those permissions, yet, when i want to assign that role to myself, it doesn't appear on the list:

Even though i see it in the roles list:

What am i doing wrong? I am finding this quite frustrating being the fact that I don't have the permissions even though I am the owner of the organization.

Thanks in advance.

Hi @oteiza-a 

Did you've tried to add this policy AT THE ORGANIZATION level of IAM ? 
Or you can use this command 

gcloud organizations add-iam-policy-binding YOUR_ORG_ID --member='user:YOUR_EMAIL' --role='roles/orgpolicy.policyAdmin'

cheers,
