I'll need to implements some special cases for not supported browsers and now must compare error with magic string for detect this situation

Describe the solution you'd like

Create token for 'Permissions is not supported in your browser' error and export them for compare with really throwed error

There is already a token for support, isn't it sufficient?

I've mean token for error message. At now lib throwing magic string if support check failed.
But, if I check permission availability first, I never get this error. Really, this closes my case. Thanks for the quick response
