Pick one area to specialise in, re-write your CV to emphasise all the things you did related to the specialisation. You can even change previous job titles to match your new field of expertise.

This is the way any field goes when the technology advances. In the 1960s most people working on computers then were effectively electronic engineers, computer scientists and software developers all at the same time. Now in 2020, you will be hard pressed to find a software company that cares about your knowledge of ohm's law and similarly you won't find an embedded electronics company that cares about your experience with state management in React.
