Trying to update composer packages with PHP 8

Question

On my dev machine I have PHP 8, I'm trying to get Composer to upgrade some packages but it keeps giving errors about the PHP version despite all the packages having updates that support PHP 8.

I've no idea how to get around this issue?

Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires abraham/twitteroauth ^1.2 -> satisfiable by abraham/twitteroauth[1.2.0].
    - abraham/twitteroauth 1.2.0 requires php ^7.2 || ^7.3 || ^7.4 -> your php version (8.0.9) does not satisfy that requirement.
  Problem 2
    - guzzlehttp/guzzle 7.0.1 requires php ^7.2.5 -> your php version (8.0.9) does not satisfy that requirement.
    - google/apiclient v2.7.2 requires guzzlehttp/guzzle ~5.3.1||~6.0||~7.0 -> satisfiable by guzzlehttp/guzzle[7.0.1].
    - google/apiclient is locked to version v2.7.2 and an update of this package was not requested.

Tried forcing a newer version that I want and still doesn't work:

composer update abraham/twitteroauth:3.0.0
