Cannot install via Composer

[hondaman900]

I'm trying to install Laravel-stripe-webhooks in a fresh localdev Laravel 8 app, and it keeps bombing out with the errors. My local dev runs on Laragon running Apache with PHP 8.1.10. However, checking PHP version in my CLI gives PHP 7.4.8 in response to PHP -v. The Laragon folks say that since Apache runs at 8.1.10 then what the CLI reports does not matter as Apache is running in 8.1.10.

Here's the error I get:

PS C:\laragon\www\stripe-laravel> composer require spatie/laravel-stripe-webhooks
Cannot use spatie/laravel-stripe-webhooks's latest version 3.7.0 as it requires php ^8.0 which is not satisfied by your platform.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require spatie/laravel-stripe-webhooks:*" to figure out if any version is installable, or "composer require spatie/laravel-stripe-webhooks:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

I tried updating PHP using Composer in my project's root directory, to no avail:

Any suggestions? I need to be able to install laravel-stripe-webhooks to be able to progress at all.
