Want to meet these guys in person? Probably will attend myself too. Got a registration already. They can invite you avoiding the hefty entrance fee. It is a huge event. https://www.iseurope.org/
I recall this is the second time covid-19 jeopardizes you being present. Last time was Amsterdam and I just encountered an empty space there.
The restrictions that South Asian people have to travel are still a lot heavier then Europe even in 2022. I might be better or just the same or even worse no one knows for sure.
