In context, you're both wrong. You're correct that § 2(G)(3)(A)(i) and (ii) explicitly name Bytedance and TikTok [1], so it is not up to presidential discretion to add more apps, but § 2(G)(3)(B)(ii) indicates that it is within the president's discretion to not enforce.

There are some paperwork qualifiers that for certain have not been met (the not-yet president almost certainly could not have briefed Congress as president 30 days prior) -- but they seem trivial to satisfy, and it would be pointless to initiate enforcement actions for an event nobody intends to follow through on
