My friend asked me to help her polish part of email in the following. Please give me some advice. Thanks a million!

"Based on the experiments and efforts I put on this manuscript, I kindly ask you to agree to list me as co-first author on this manuscript. I understand last spring you had visa issue and family reunion matters. However, I think considering all the time and experience I consumed on this manu, it is worth for a co-first authorship. Please let me know what you think."
