What Slack App Should I use for Advanced Approvals?

I have advanced approvals, but I'm using it in a pretty basic way, not sure if that matters. What is the best slack app to use for Salesforce approvals going forward?

I feel like there are so many I don't 'know which to choose from.  

I was peaking around and found this article (https://help.salesforce.com/s/articleView?id=sf.slack_apps_digital_hq_approvals_use.htm&type=5). It says to use the Salesforce for Slack app for approvals. It doesn’t mention the Salesforce CPQ Advanced Approvals app. 

I also found this article (https://help.salesforce.com/s/articleView?id=sf.slack_apps_options.htm&type=5) also. Also, doesn't mention Salesforce CPQ Advanced Approvals app.
