I'll send you a link but just so you know what these things look like. If you want to buy, search around for the lowest price on Amazon, as they're basically all the same. Just search for smartphone eyepiece adapter.
Type 1 has the circular clamp and won't accept eyepieces with beveled edges most of the time, and is only for 1.25" eyepieces. I've used two of these. I left one of them in the observatory I volunteer at before quarantine started so I had to buy another one since no one's allowed in.
Type 2 has a clamp which might accept more types of eyepieces, but it looks like it'd be harder to get the phone camera centered. I haven't used this type.
