Unable to install Restcord alongside symfony 5 and guzzle 7.2

[BigPino67]

I've got an error when i try to install Restcord (release or dev-master)

composer require restcord/restcord
Using version ^0.5.0 for restcord/restcord
./composer.json has been updated
Running composer update restcord/restcord
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 restcord/restcord ^0.5.0 -> satisfiable by restcord/restcord[0.5.0].
    - restcord/restcord 0.5.0 requires guzzlehttp/guzzle ^6.3 -> found guzzlehttp/guzzle[6.3.0, ..., 6.5.x-dev] but the package is fixed to 7.2.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

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

What can I do?
