Transfer work and send a request message to the leader.

Just write: I am XX, and I am currently working in XX post. Because of XX, I want to transfer to XX. I have XX work experience in my previous job, which can meet the requirements. Can the leader recommend it to me? Thank you very much.

Why do you ask for text messages? A leader is just a leader in your work. Everyone is equal in personality. It's best not to think so, let alone say so.

It's best to talk about the job transfer in person. You can invite the leaders out for dinner in private. By the way, if you are not eloquent or embarrassed to speak, you can find a glib middleman or a respected person or a red man in front of the leader to help you talk together. Pay attention to just eating, don't give gifts, if you want to give gifts, give gifts after the job is done. A little personal advice, for reference only.
