UI explanation | payment buttons on a workstream

I have a client who has accepted my proposal and got notified of it but when I open the project I find it's still open for other proposals. Is this normal? Isn't it supposed to have a sign or something clarifying someone was hired here?
I have almost completed the task but not sure about the next step. The escrow has 1 hour pay which is not really the full price and I can see three buttons in the chat: 'raise invoice', 'request deposit', 'request auto pay'.

When and which each one is used for?
After confirming with the client, should I just send the files and wait for the client to accept the work?

P.S: It's hourly based project not fixed price.
