In my opinion the key thing is find an employer/interviewer that emphasis more on high level things than specific stack, you're mid-senior, I think it would be natural for you to discuss architecture, design, manage tech debts, communication, people business, these kinds of things during interview. Depending on the market but I think (or I hope) it wound't be hard to find these sensible interviewers in the market.

Second is practice, if you were to switch your stack, then a bit practice IMHO is still needed, build something, and keep an eye on how the common things handled in this different stack, say in web dev, global exception handling, routing, authn and authz, etc. Once you've mastered these you should feel confident talk about these during interview.
