https://api.us.nylas.com/v3/grants/{grant_id}/templates/{template_id}/renderRender a template
Renders the specified template with the provided variables. Nylas looks for a grant-level template with this ID first. If the grant doesn't have one, it renders the application-level template with the same ID.
Works with an API key, an access token (use /v3/grants/me/ in place of the grant ID), or an IAM API key with the templates.render permission.
