"Glow" FX is your friend but not sure that's available in the free Davinci version (exists in AE as well, Premiere doesnt have it but there are good YT tutorials to fake it in Premiere). There's an even better one in the paid Davinci Studio Version called "Halation" and the best is in a plugin called filmconvert Nitrate. But tbh this effect looks a little more bespoke and looks like what Benny Maglinao is doing to the FA stuff. I've heard he has a setup that feeds the Clip into an old TV and films it off that, which sounds like a big thing to set up but once in place is probably quicker than what you'd have to do digitally to really nail this look. Purely creatively I think this look is so strongly Maglinao's that you'll always look like an uninspired ripoff when copying it.
