Any API to add access permissions for a specific repo for a Github app?

I have an installed Github app in my organization for which I allow access to only a subset of the repos.   I’d like to use an API to programmatically add those repo access permissions for that app.  Is that possible?  If not, is it planned?

HI @gscott,

Thanks for being here! When you create a GitHub App, you set the permissions that define the resources the app can access via the REST API v3. I hope this helps!
