Sample Code Snippet

// Works when it does not exists
vaultClient.V1.Auth.AppRole.WriteRoleAsync("my-role", new AppRoleRoleModel
        {
            TokenPolicies = new List<string> {policy},
            BindSecretId = false,
            TokenTimeToLive = 30,
            TokenMaximumTimeToLive = 30,
            TokenBoundCIDRs = new List<string> { "127.0.0.1/32" },
        }).Wait();

// Does not work after it's created
vaultClient.V1.Auth.AppRole.WriteRoleAsync("my-role", new AppRoleRoleModel
        {
            TokenPolicies = new List<string> {policy},
            BindSecretId = false,
            TokenTimeToLive = 30,
            TokenMaximumTimeToLive = 30,
            TokenBoundCIDRs = new List<string> { "127.0.0.1/32" },
        }).Wait();

Any additional info
As far as I can see, the AppRole API does not expect a local_secret_ids property when updating a role. https://developer.hashicorp.com/vault/api-docs/v1.14.x/auth/approle#create-update-approle.

A possible solution could be to have a UpdateAppRoleModel and CreateAppRoleModel where the CreateAppRoleModel could inherit UpdateAppRoleModel and define the property local_secret_ids.

I know that there are API endpoints to update certain parts of the role but I want to give it my full role definition when to modify everything in one request instead of doing many small ones.
