[FEATURE] Add status of transfer approval in progress

[YoshihitoAso]

Is your feature request related to a problem? Please describe.

There is a lag after a transfer is approved before the status is reflected in the transfer approval history.
We have received a request to display the status of transfer approval in the client application.

Describe the solution you'd like

Add the status of transfer approval in progress so that the status can be returned in the history of transfer approval.
