in case: be open selling your domain? just as one possibility to avoid lengthy legal disputes / costly interactions with lawyers!?
you mentioned above, you are "from a poor country" ... several k or even some 2 digit k of us$ / euro - depending on the actual name - might be a decent pain-compensation for "loosing" your domain and carry you further in your country than a stupid personal domain with nice email-addresses attached to it ;))
Offering to sell the domain will probably count as evidence that you've registered it in bad faith rather, and make it easier for a trademark owner to win a dispute.
Don't confront them to offer them anything, let them come to you.
Trademarks dont mean you own a word, they mean that the use of that word is to be protected from passing-off/impersonation (intentional or otherwise).
So by all means call yourself Coke - just dont market yourself as a soft-drink (or whatever other categories the mark is held and/or defended in).
If the person holds an asset and isn’t doing anything malicious with it there is zero reason they should be forced to give it up just because some corporation wants it.
