Are there any 3rd party alternatives to power automate/flow for SharePoint server 2019?

Question

My organization would like me to implement an approval flow for our new communications site. The organization uses SharePoint server 2019 but does not want to use a gateway for Power Automate/Flows. Are there any feasible 3rd party options I could utilize to make an approval flow?

Answer 1
