Refit 6 not working when android project built with unity

Question

I'm using Refit 6 in unity for rest calls but when project is built for Android getting below error.

Message: MissingMethodException: Constructor on type 'Refit.Implementation.Generated+*InterfaceName*' not found.

I tried adding link.xml but didn't help.

Any help on this will be useful.

It looks like they added support for code generation in 2021.2 (https://docs.unity3d.com/2021.2/Documentation/Manual/roslyn-analyzers.html)

But how you use that with refit, I don't know. I'd like to get refit working with Unity as well.
