Hey @Jayclifford345, congrats on your first contribution! We don't typically add this particular video to the What's new page, but let me loop in someone else to get their opinion. @mjseaman, what do you think of this addition as a regular thing?

Hi @imatwawana, thank you very much :)! I have mostly been in the Loki docs so excited to add something to the main Grafana repo to :D. ah no worries the content team mentioned I should try and get it posted in the docs under what's new since we also had the feature videos there.

I'll leave it up to @mjseaman. If he approves, I'm fine with it!

Hi, @imatwawana do you think we could give this a merge? :)
