doctl serverless connect - required API token scopes?

I have a few namespaces which host Functions based in different regions. I’d like to use doctl to switch between the different Function namespaces for easy deployment, however I’m running into an issue when I attempt to use doctl serverless connect. When running this command I receive a prompt to select the namespace I would like to connect to. After making my selection I receive the following message:

Error: GET https://api.digitalocean.com/v2/functions/namespaces/{namespace-id}: 403 You are not authorized to perform this operation

I’ve done the following troubleshooting:

• Used doctl auth list to ensure that I was using the correct auth context
• Created a variety of tokens with different auth scopes, init a new auth context in doctl and attempted to use doctl serverless connect again. In all situations I ensured the token had full function scope

So far I’ve only been able to successfully use this command when using an API token that has the full access scope. What are the granular scopes I can enable so I can use doctl serverless connect without requiring an API token that has full access enabled?
