Hello @abolkog !

Thank you for this integration.

Can you please add the documentation related to the settings of this provider.
Here is the page where you have to add the documentation.
To do so, you will have to update the docs/v3.x/plugins/users-permissions.md file.
For the format, please, follow the same as the other provider.

Thank you.

[abolkog]

Hey @lauriejim I have added the documentation.

[abolkog]

hey @lauriejim any chance we can get this PR reviewed 😅

Hi @abolkog let me poke @petersg83

[petersg83]

Hi ! Thank you for your contribution, I just tried it and it works well :)
I've noticed a few typos, can you fix them please? Then we're good to merge!
Also if you can rebase your branch on master so there are no conflicts it would be perfect. Thanks!

[abolkog]

Thanks @petersg83 for the review. I have fixed the typos and rebased to master.

[petersg83]

Hi ! Thanks :) It seems you have an unexpected file in your PR : packages/strapi-plugin-users-permissions/admin/src/components/PopUpForm/index.js
Can you fix that please? :)

[abolkog]

@petersg83 removed the additional file
