AWS Cloud9 showing `no access` under permission, any idea?

Question

I am trying out a workshop for AWS EKS using Cloud9, and have this properties set:

aws cloud9 describe-environment-memberships --environment-id 23104b5e40ee441ab9cefb8b7f7164dc
{
    "memberships": [
        {
            "permissions": "read-write",
            "userId": "AIDATYVU6WKIS6LOM4NXB",
            "userArn": "arn:aws:iam::259151278737:user/eks-workshop-gitops",
            "environmentId": "23104b5e40ee441ab9cefb8b7f7164dc"
        },
        {
            "permissions": "read-write",
            "userId": "AIDATYVU6WKITNU6UKSNC",
            "userArn": "arn:aws:iam::259151278737:user/Sandbox_contributor",
            "environmentId": "23104b5e40ee441ab9cefb8b7f7164dc"
        },
        {
            "permissions": "owner",
            "userId": "AIDATYVU6WKIV2ZOAKKMY",
            "userArn": "arn:aws:iam::259151278737:user/it.terraform_user",
            "environmentId": "23104b5e40ee441ab9cefb8b7f7164dc"
        }
    ]
}

My IAM is under that Sandbox_contributor as seen above. Status of my Cloud9 environment is as follows:

aws cloud9 describe-environment-status --environment-id 23104b5e40ee441ab9cefb8b7f7164dc
{
    "status": "ready",
    "message": "Environment is ready to use."
}

detail status of my cloud9 environment:

aws cloud9 describe-environments --environment-id 23104b5e40ee441ab9cefb8b7f7164dc
{
    "environments": [
        {
            "id": "23104b5e40ee441ab9cefb8b7f7164dc",
            "name": "eks-workshop",
            "description": "",
            "type": "ec2",
            "connectionType": "CONNECT_SSH",
            "arn": "arn:aws:cloud9:ap-southeast-1:259151278737:environment:23104b5e40ee441ab9cefb8b7f7164dc",
            "ownerArn": "arn:aws:iam::259151278737:user/it.terraform_user",
            "lifecycle": {
                "status": "CREATED"
            },
            "managedCredentialsStatus": "DISABLED_BY_DEFAULT"
        }
    ]
}

However when I login to the AWS console, under Cloud9 resources, it still shows as No Access under Permissions and I still can't open the IDE as its greyed out.

Each Cloud9 environment has one and only one owner, who is the environment creator. You probably creating the environment with one user/role, and try to access it with another. Try to create the environment with the same user/role as the one who will eventually use it from the console.
