Firebear Improved Import & Export 3.8.7

[work]

I think OP should be careful with this one because there is actually 2 versions of microsoft/microsoft-graph. Version 1. and version 2. I tried Firebear 3.8.7 with version 2 and got errors when installing Firebear. I recommend using latest of version 1:
composer require microsoft/microsoft-graph:1.110.0

When PHP versions are different, you may receive different version files, so no suggest use same special version number
