Need Docs on how to Deploy SWA using Azure Marketplace Offer

We are an app shop that is trying to deploy an Azure Marketplace Software as a Service (Saas) offer. One item that is not clear is now to accomplish this with an Azure Static Web app.

**Problem**
All the current documentation has been released connecting SWA to Git Repos, which is nice, but since we are deploying through azure marketplace we don't want to connect our Company Repo to every deployed solution.

**Describe the solution you'd like**
We would like to see a documented way to create a build of the app and deploy it using a Zip file directly into the SWA. We could do a local build of the SWA and store that on a Blob storage create a SAS key. Then instead of link the SWA to a repo, point the SWA via property to the storage account.

Then we would use an API call to "Refresh" the files in the SWA, this would be commanded by a PowerShell script that lives in the bicep template.

**Describe alternatives you've considered**
We are currently testing the deployment using a docker container and the SWA CLI deployment. The docker container spins up and then the bicep template runs scripts that produce the build and publish from docker.

Has anyone else had success deploying an SWA from the Azure Marketplace?
