Composer install dependency issue

[megacarlossm]

I'm using Laravel 7.x, this Problem happened when I tried to Require this package with composer.

  Problem 1
    - Installation request for googleads/googleads-php-lib ^49.0 -> satisfiable by googleads/googleads-php-lib[49.0.0].
    - Conclusion: remove guzzlehttp/guzzle 6.5.5
    - Conclusion: don't install guzzlehttp/guzzle 6.5.5
    - googleads/googleads-php-lib 49.0.0 requires guzzlehttp/guzzle ^7.0 -> satisfiable by guzzlehttp/guzzle[7.0.x-dev, 7.1.x-dev].
    - Can only install one of: guzzlehttp/guzzle[7.0.x-dev, 6.5.5].
    - Can only install one of: guzzlehttp/guzzle[7.1.x-dev, 6.5.5].
