Normally the tag to use in this case is "Co-developed-by".

https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html#when-to-use-acked-by-cc-and-co-developed-by

"A Co-Developed-by: states that the patch was also created by another
developer along with the original author. This is useful at times when
multiple people work on a single patch. Note, this person also needs to
have a Signed-off-by: line in the patch as well."
