update comment not working, PR gets multiple comments

update comment is not working, example:

this is causing multiple comments to appear with each new commit, instead of new commits replacing old comments.

Our PRs are getting multiple comments from nextjs-bundle-analysis github action. We get a comment when opening a new PR, and then a new comment on each new commit pushed.

For example:

Previously, the comment would be replaced with each new commit.

We have other github actions that do not have this problem.

Any help would be greatly appreciated. Thanks!
