I figured out a solution, which I'm posting here since my question is at the top of the search results. I'll leave out the parts specific to my project since a more generic solution might be more useful to anyone else with a similar problem.

```
import sys
from PyQt6.QtWidgets import QApplication, QMainWindow, QWidget, QTextEdit

class textBuffer(QTextEdit):
	def mousePressEvent(self, e):
		self.link = self.anchorAt(e.pos())
		if self.link: # If a link is clicked...
			print(f"Clicked on {self.link}") # Output its message. You can alternatively call a function here or open the link in a browser if you want.
			# self.link = whatever you set the href to (see below).

class AppWindow(QMainWindow):
	def __init__(self):
		super().__init__()
		self.setWindowTitle("Clickable Links")
		self.setGeometry(0, 0, 800, 600)
		self.buffer = textBuffer() # Create a QTextEdit widget from the class above (won't work without it)
		self.buffer.setReadOnly(True)
		self.setCentralWidget(self.buffer)
	def addLinks(self):
		messages = ["Hello there", "Hi", "New message"]
		for message in messages:
			self.buffer.append(f'{message} <a href="{message}">Link Text</a>') # Append each message to the QTextEdit as an HTML formatted link
			# Set the link text and href to whatever you want. Displaying the message first is optional

app = QApplication(sys.argv)
window = AppWindow()
window.show()
window.addLinks()
app.exec()
```
