If it was an 'inquiry' you made not a 'request to book', then all inquiries expire after 24 hours, so you can start the whole process again. (You're obviously not needing anything urgently within 24 hours, if you're in the UK, cos calendars are blocked till 4 July!).
To avoid losing her 100% response rate, the host must respond within 24 hrs, but that does not need to be by checking 'approve' or 'decline' - a written reply will suffice.- And it sounds like she's already responded, so job done.
I know you can withdraw 'request to book', to protect your host from black marks for declining; I thought it WAS possible to withdraw the 'inquiry', but I've never used the platform as a guest, so not viewed the tab....
