Can I legally host an in-person event in Thailand with a DTV Visa if my clients are primarily foreigners?

DTV Nuanced question.

I understand that I’m allowed to work remotely in Thailand with clients from outside the country but not to work with Thai clients or be directly involved in Thai businesses.

But, how about in-person events held in Thailand, organised by DTV holders who target foreign clients?

From my experience, I’ve seen some businesses in Thailand (for example organized events, or retreat centers) who invite foreign guest teachers for short-term events while the teachers are on tourist visas (short term business), and nothing wrong or ilegal seems to happen.

With a DTV Visa, would I be able to legally:

- Held an in-person event in Thailand at a venue that regularly hosts other foreign guest teachers for similar in-person events?

Clients attending such events would mostly be foreigners.

Do you have any advice on this?

Is there someone else you recommend I consult? (Currently consulting a Thai accountant).

Thank you so much for your help!
