Release for trigger finger injury advice

[Team4LongGun]

Hunting buddy's index finger is severely injured. Was using a Scott Shark. Which thumb release would you recommend for hunting, so he can draw and fire with no involvement with index finger?

TIA

How limited is his index finger?

Like, he can grip and hold a release fine?

There's a few options that are thumb buttons but still have a wrist strap too.

For a relatively cheap hunting release that is still decent, I like the spot hogg whipper snapper. From there, they get a lot more expensive and feed into individual preferences.

Here's an example of one that can likely be used without any use of the index finger.B3 Exit Hunter Thumb Release (Green Anodize) – Lancaster Archery Supply https://share.google/SuJovGNN88gKAwS8q

He can't use it at all. His finger went sideways in a freak work accident, and the tip to first knuckle is broken/torn and surgery may be needed if it doesn't heal in splint. They don't want to do surgery as it will limit range of motion/usage permanently.
The rest of his hand is fine, that's why we figured a thumb release will be good. I just never used one all these years, and wanted to get some guidance on what to try and what to avoid.
