Let me 'fess up that I'm not an expert on cellular antennas by any means, but I see that your description of what's going on with your phone seems to match up with the solution description for what the French site SOSav calls the External Speaker & GSM Antenna.
[quote]Does your ***iPhone SE 2020*** no longer make any sound? Does the sound mute when you watch a video? Doesn't it ring anymore? The sound remains weak while the volume is at maximum? And yet everything works when you call? This is because it is a separate speaker! In your case, the iPhone SE 2020 ***external speaker*** is faulty. It manages all the sound of the iPhone except calls. Also on this speaker is the ***GSM antenna*** . So if you have problems receiving 3G / 4G network, this is also the part that you should change. The experts at SOSav are there to support you throughout the maneuver through this illustrated ***repair guide*** and each step is detailed in detail to prove to you that repairing your iPhone SE 2020 is possible and economical.[/quote]

That would be my first pass at fixing this problem, to replace that antenna. It's actually glued to the speaker, but is sold separately. The iPhone 8 and the SE 2020 use the same parts for both, so finding an antenna for either will work. Here's an example that came up on a cursory search; I usually start by checking eBay, Amazon and AliExpress, depending on my desired cost vs. shipping time tradeoffs.

Don't forget to pick up a sheet of precut adhesive for sealing the display back up against water when you're done! Personally I usually buy a couple because they're easy to mess up and if they don't go on right the first time, you usually can't recover them and just end up with a tangled ball of glue. So having an extra on hand means you won't have to wait to finish your phone until you can reorder.
