Appears to not be working in 10.1.5 on fresh Amazon Lightsail Bitnami

Problem/Motivation

Field Group does not show at all in Field Type for both existing and new fields.

Steps to reproduce

This is happening on a fresh instal that has had no modifications at all, and virtually no content.

Install fresh Amazon Lightsail Drupal Bitnami image.
Updated to Drupal 10.1.5.
Installed Field Group 8.x-3.4 via the Drupal web interface from https://ftp.drupal.org/files/projects/field_group-8.x-3.4.tar.gz

Checked logs. Cleared cache. Nada.

Proposed resolution

Remaining tasks

User interface changes

API changes

Data model changes
