Integrating Rails app using React framework with Azure

I'm trying to figure out the best course of action to integrate a Rails app with Azure cloud services. I'm working on a team project where I'm leading the cloud side of things, using Azure. We are making a web app using Rails and utilizing the React library. We are also using Azure SQL for the DB. I'm wondering if anyone can help with figuring out the best course of action to integrate our app with Azure and hosing it on the cloud. My goal is to have our project connect to the cloud so that I'll be able to set up a testing environment so that someone can interact with our app without having the environment set up (someone like a stakeholder for example in another part of the country, etc). So far, my services include a Static Web App, database, and App Service. I also have DevOps set up mirroring our main repo in GitLab. They are not all completely set up/connected. I'm trying to figure this out using a static web app, but having some issues setting it up and connecting the API. I've been looking at a lot of resources and the Azure docs, but a lot of it has to do with starting things from the ground-up, whereas we have a lot of stuff built already. Does anyone have any steps, tips, or resources that will be helpful moving forward? I feel like I've just been going in circles. I hope this question was clear enough. This is also a school project and we are trying to keep things free. We do have a small budget if necessary. Thanks in advance!
