I don't have experience of this on Lastpass, but I know that 1Password users on Mac need to download the desktop app to install the Safari extension.

LastPass iOS Safari extension just asks to ‘Unlock LastPass’, then when I tap it, it just opens the LastPass app vault. What’s the point of it?
All I know is that is that as the years go by it gets jankier and jankier. More on reddit.com

December 17, 2021 -

Hi, I'm really struggling with this, I've just got a new macbook and unable to download the lastpass extension, it just sends me to the desktop and downloads the desktop app. I'm completely lost, the documentation says to download the safari extension, but I simply can't seem to get to it. Any help would be much appreciated as LastPass support guy couldn't seem to help either

lastpass extension not in safari - Apple Community
LastPass password manager Why is the LastPass Password Manager program not available for downloads in the iTunes or Apple store for use in Safari on the MacBook? Several other password manager programs are available to download as an app but not LastPass. Instead, I have to download the extension from their website, open it in applications and enable it in Safari Preferences.
