How to manually apply maintenance to ESPHome device

I have an Athom Presence Sensor Model PS01 which I was unable to apply maintenance over the air due to errors about file size being too big. I was reading about doing this manually and I have managed to download the file to my MacBook, I have a USB-C data cable so what are the steps involved in manually applyin the maintenance over the wire?
I am assuming that I select the option Plug into this computer and it states that I need to download the project which I have done, then I need to Open ESPHome Web but when I click on this i am taken to the ESPHome home screen and I don’t see any reference to ESPHome Web.
Help please, am I on the wrong track?

Click on what? I’m unclear when this prompt is appearing.

If you have compiled and downloaded the file, then you can get to ESPHome Web by clicking install, choose Plug into this computer, then there is a link to ESPHome Web below.

That takes you to this page:

You can simply use that link I pasted above to install if you already have the files.

Hi Daryl,
Thanks for your help.
