JGit Java Changing the date of the last commits - jgit

Question

I'm trying to make the following git commands using the JGit library:
git rebase -i HEAD~2
git commit --amend --reset-author --no-edit --date 2022-07-07T15:30:00.0000000+03:00
git rebase --continue
git commit --amend --reset-author --no-edit --date 2022-07-07T15:33:40.0000000+03:00
git rebase --continue
To do this, I have to switch to the branch I want and then run these commands.
This is what I'm trying to do:
File yourFile = new File("...\\.git");
FileRepositoryBuilder repositoryBuilder = new FileRepositoryBuilder();
repositoryBuilder.setMustExist(true);
repositoryBuilder.setGitDir(yourFile);
Repository repository = repositoryBuilder.build();
Git git = new Git(repository);
git.checkout().setName("main").call();
RebaseCommand.InteractiveHandler squashHandler = new RebaseCommand.InteractiveHandler() {
#Override
public void prepareSteps(List<RebaseTodoLine> steps) {
for (RebaseTodoLine step : steps.subList(1, steps.size())) {
try {
step.setAction(RebaseTodoLine.Action.SQUASH);
step.setShortMessage("");
} catch (IllegalTodoFileModification e) {
throw new RuntimeException("Couldn't squash commit " + step.getCommit().name(), e);
}
}
}
#Override
public String modifyCommitMessage(String commit) {
return commit;
}
};
git.rebase().runInteractively(squashHandler).setUpstream("HEAD~" + 1).call();
And then I don't know what to do and I'm not sure what started out right.
I think the next step should be something like this:
git.commit().setAmend(true).<anything else>
Please tell me how to execute the above git commands with JGit. I tried to find documentation that describes everything in a very clear language, like this
git command: git rebase -i HEAD~2
JGit code: git.rebase().runInteractively(squashHandler).setUpstream("HEAD~" + 2).call();
But I couldn't find anything like that, and reading the documentation, I almost shot myself :) Thanks
