Is there a way to temporarily rebase a feature branch?

Question

How can I take the set of commits in my branch, and rebase them to a temporary branch, and then rebase back to main?

More details- My branch, my-branch depends on another code change feature1 that a co-worker should push soon. I don't want to wait for him, so I created temp-feature1 that contains the desired change. My plan was to rebase my-branch above temp-feature1, and rebase again to main once main contains the desired commit.

This is what I did:

During develop

git checkout main
git checkout -b temp-feature1
# commit temp changes that I want to depend on (feature1)
git checkout my-branch

And now I can develop without waiting for my college's commit.

Once feature1 is merged to main I thought I can simply do -

git checkout main
git pull
git checkout my-branch
git rebase main

And remove my temp-feature1 commit from the log, becuase it's already in main.

However, the rebase to main returned

Current branch my-branch is up to date.

And temp-feature1 commit was still there.

Is there any way to get this workflow?
