Jenkins for Jira (Official) - Connect a Jenkins server button is missed

[Artem Epishov]

Hi all, I try to follow instruction for Jenkins for Jira (Official) plugin integration:

Set up a webhook in Jira

After installing the "Jenkins for Jira" app on your Jira site, you’ll need to set up a webhook:

1. In Jira, go to Apps > Manage your apps.

2. In the left sidebar, under "Apps", click the link to the "Jenkins for Jira" app.

3. Click on "Connect a Jenkins server".

4. The app will remind you to install the Jenkins plugin. Click on "Next".

But "Connect a Jenkins server" button is missed in plugin configuration. 

Could you please help me with suggestion suggestion should I use another plugin for integration or this bug will be fixed?
