Bundling Mono Framework with Duplicati on macOS (Big Sur)

I am trying to bundle the mono framework (6.12.0.140) with the Duplicati application so that I can distribute the application without having to worry if the mono framework is installed in the local macOS (11.4 Big Sur) environment. When running the command mkbundle, I get “Error: Cannot find assembly …” Please advise on the proper command to try.
