Hi @rohitratannagar , thanks for the pr 🎉
Which main branch are you on? I have pulled this PR code and exported the dynamic-home-page and quickstart plugin package into the latest rhdh main branch code to test this out. This is what I got.

Let me know if I have missed anything 👀

Hi @HusneShabbir , which code base are you on? I was on latest RHDH main branch and exported the latest dynamic-home-page and quickstart plugin package to test out this pr. Did you do anything else I could possibly miss?

@ciiay I used the latest RHDH main branch and exported the dynamic-home-page with @rohitratannagar's changes and just added the quickstart config, was able to successfully test it this way
