How to clear cache in GitHub Actions?

I am working on an R package and using GitHub Action (GHA) as a Continuous Integration (CI) provider. I cache R packages (dependencies) by using actions/cache . And now I want to clear all cache. How can I do that?

I also asked this question on Stack Overflow (with no answer yet) and I provided my code examples there:

Hi @GegznaV,

Glad to see you in Github Community Forum!

Cache is stored on Github server, currently it’s not supported to clear it manually. GitHub will automatically remove any cache entries that have not been accessed in over 7 days.

Please check the Usage limits and eviction policy for more details.

Thanks
