could you please assign this to me.

Hi @Krishnag09, I believe tickets are not typically assigned outside of the Wagtail core team, but do feel free to pick this up and start working on it :)

[Krishnag09]

I have the changes ready but would need access to push.

[jams2]

Hi @Krishnag09 , you should:

1. create a fork of this repository in your own github account;
2. clone your fork to your computer;
3. create a new branch for your work;
4. commit your work to your new branch;
5. push those changes to your github repository; and
6. open a pull request on this repository, from your branch targeting main.

Once your changes have been reviewed, tested, and any necessary changes have been made, a maintainer of this package will merge them.
