Connect URL - Cannot edit URL

Hi.
I am new to the community and love the look of the application. I am using Zabbix 4.4 on Ubuntu Bionic and have Grafana installed along with the Zabbix plugin. I do have an issue which seems different than other users have experienced though it has the same/similar error:

Could not connect to URL

Zabbix-data-source-error

I have searched and read and unfortunately I cannot resolve that on my own… The URL field is not editable.

Does anyone have any tips/suggestions/workarounds they can share?

Thanks in advance.

What I also have seen is that the ability to import Zabbix dashboards is missing after installing the plugin. I only have enable or disable:
