Different builds of the same package are considered as different packages

I'm using "WixToolset.Sdk/6.0.0" to build my MSI installer. However, each time I rebuild the MSI, it produces what appears to be a different product. For example, I can install the new MSI even if the previous version (from the last build) is already installed.

I expected that running the new installer would detect the existing installation and display the "Change, Repair, or Remove" dialog. Instead, it shows the standard installation dialog, and I end up with what looks like two identical products installed side by side.

Is this expected behavior? Should I configure something to ensure that rebuilds produce MSIs that are recognized as the same product?

I think the product ID has to remain the same for it to be considered the same product. The ID attribute here: https://docs.firegiant.com/wix3/xsd/wix/product/.

By default if it is not specified or set to "*" it will generate a new ID each build.
