Paypal api – updating composer / installing a new package conflicting packages

I wanted to install a new package in a Laravel 7 application. I have tried direct composer require command and tried manually entering package name and updating composer command but both times it returns error as follows.
while using command ‘composer require simplesoftwareio/simple-qrcode’

 Problem 1
- chumper/zipper v1.0.0 requires illuminate/support 5.x -> found illuminate/support[v5.0.0, ..., 5.8.x-dev] but these were not loaded, likely because it conflicts with another require.
- chumper/zipper[v1.0.1, ..., v1.0.3] require illuminate/support ^5.0 -> found illuminate/support[v5.0.0, ..., 5.8.x-dev] but these were not loaded, likely because it conflicts with another require.
- Root composer.json requires chumper/zipper ^1.0 -> satisfiable by chumper/zipper[v1.0.0, v1.0.1, v1.0.2, v1.0.3].

while using command ‘composer update'(with or without writing the new package details)

Problem 1
- Root composer.json requires robincsamuel/laravel-msg91 dev-master -> satisfiable by robincsamuel/laravel-msg91[dev-master].
- robincsamuel/laravel-msg91 dev-master requires guzzlehttp/guzzle ^7.0.1 -> found guzzlehttp/guzzle[dev-master, 7.0.1, ..., 7.2.0] but it conflicts with your root composer.json require (~6.0)

  Problem 2
    - Conclusion: don't install chumper/zipper v1.0.1 (conflict analysis result)
    - Conclusion: don't install chumper/zipper v1.0.2 (conflict analysis result)
    - Conclusion: don't install chumper/zipper v1.0.3 (conflict analysis result)
    - Root composer.json requires chumper/zipper ^1.0 -> satisfiable by chumper/zipper[v1.0.0, v1.0.1, v1.0.2, v1.0.3].
    - Conclusion: don't install laravel/framework v7.0.1 (conflict analysis result)
    - Conclusion: don't install laravel/framework v7.0.2 (conflict analysis result)
     .........
    - Conclusion: don't install laravel/framework v7.30.1 (conflict analysis result)
    - Conclusion: don't install laravel/framework v7.30.2 (conflict analysis result)
    - Conclusion: don't install laravel/framework v7.30.3 (conflict analysis result)
    - Conclusion: don't install laravel/framework v7.0.0 (conflict analysis result)
    - chumper/zipper v1.0.0 requires illuminate/support 5.x -> satisfiable by illuminate/support[v5.0.0, ..., 5.8.x-dev].
    - Only one of these can be installed: illuminate/support[dev-master, v5.0.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev], laravel/framework[v7.0.0, ..., 7.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it.
    - Root composer.json requires laravel/framework ^7.0 -> satisfiable by laravel/framework[v7.0.0, ..., 7.x-dev].

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