I have recently started working on a chrome extension which uses manifest v3. I see a lot of APIs being different from v2.

So what happens when a user who is running an older version of chrome? As a developer, do I need to accommodate different chrome API calls based on the version that my extension is running on?

As an example this code works in the current version chrome.runtime.getURL('logo128.png').

However, in the older versions chrome.extension.getURL('logo128.png') works.

Any help in this direction is much appreciated! Thanks!
