Family Visit visa is on hold for now due to covid. That's why indian Nationality isn't coming in metrash. If you are working in qatar for a government company, then you can apply for family visit visa by visiting gharaffa immigration center but it is on hold for people working for private companies. No update as of now as when it will open for private companies. As per rumors, it should open in January 2021 but nothing official.

Also the issue of only the first name, in that case, I don't think you will be able to apply through metrash as it won't allow you to go ahead without entering the last name.
In that case you can visit gharaffa immigration and apply manually by filling a form. Form can be easily filled by a typing center for 10 rial. A typing center is available near to gharaffa immigration.

I hope this helps.
