Add date to Confluence page via message in slack

[John]

My team wants to use Confluence to capture quick snippets of information on a project we are working on. The data is pretty simple i.e. "spent 10 mins on jira 1001".

Ideally we would like to do this by sending a message to a specific slack channel.  Has anyone set up this functionality before? Is it possible with this app? https://www.atlassian.com/blog/confluence/confluence-cloud-app-for-slack
