React with @azure/msal-browser (i.e. V2) will force a PKCE code challenge with a (default) code challenge method of S256 for an SPA with authorization_code flow.
From memory, I don’t believe that thenetworg/oauth2-azure, greew/oauth2-azure-provider or stevenmaguire/oauth2-microsoft providers offer PKCE themselves, but thephpleague oauth2-microsoft generic provider does so – you need the getPkceCode() and setPkceCode methods (see https://oauth2-client.thephpleague.com/usage/)

And note that for PHPMailer to work, your scope permissions should be “offline_access https://outlook.office.com/SMTP.Send"

Thanks @decomplexity for your response. I'm trying to find a package with React to replace msal-browser and allows me to pass my custom code_challenge and code_chalenge_method

But I understand that the implementation of getting the pckecode is delegated to the inheriting class. In the GenericProvider class there is no way to be able to get this code in the case of Azure AD.
