Thank you Chris for your input, what do you think which one is the best in your opinion? I think this module is very important, so I wonder why Odoo did not include it in Odoo 13?

Sorry, I haven't tested any of these apps, so I don't have any recommendation.

Odoo will always have a lot of third-party apps. Sometimes the same features will be added to the official Odoo apps, but often they will prioritize something else. I think we'd all have different opinions about what should be the top priority!
