You simply have to try something like that to gain experience.
Of course, the language barrier is an additional complication.

Since Corona, online meetings have become standard for me. On the one hand, it is very relaxing not to have to go on business trips. On the other hand, such a meeting also saves a lot of time. The travel time, accommodation costs, etc. are eliminated.

However, there are disadvantages, which you have already mentioned.
For example, at training sessions it is always an advantage to be able to talk to other participants during the breaks. This is not the case with online meetings. In addition, the participants are less likely to ask questions.

Ultimately, it depends on the occasion whether such an event makes sense online. I like to do both, depending on what the occasion is.
