Hi! I'm trying to install lib, I use composer require coinbase/coinbase-commerce but I get error:

Your requirements could not be resolved to an installable set of packages.

Problem 1
- coinbase/coinbase-commerce v1.0.0 requires guzzlehttp/guzzle ^5.0 -> found guzzlehttp/guzzle[5.0.0, ..., 5.3.4] but it conflicts with your root composer.json require (^7.5).
- coinbase/coinbase-commerce[v1.0.1, ..., 1.0.11] require guzzlehttp/guzzle ~5.0|~6.0 -> found guzzlehttp/guzzle[5.0.0, ..., 5.3.4, 6.0.0, ..., 6.5.8] but it conflicts with your root composer.json require (^7.5).
- Root composer.json requires coinbase/coinbase-commerce * -> satisfiable by coinbase/coinbase-commerce[v1.0.0, v1.0.1, 1.0.11].

I trying composer require coinbase/coinbase-commerce:* -W but I get some issue
