What do I need to have in the manifest.xml file under <Host> to be compatible with Premiere Pro 14.8

Hello,

I have several Premiere Pro extensions that work in the newest version which is 14.8 at the time of writing this. However Adobe Exchange will show that compatibility to be 12.0 - 14.5 if I have the following entry in my manifest file:

<Host Name="PPRO" Version="9.0" />

I asked the CC Integrations team and they advised to put 13.0 instead of 9.0.

Then the product compatibility shows up to be:

Premiere Pro CC (2019) 13.0 - CC (2021) 14.5

Either way it doesn't say that it's compatible with 14.8.

And now one of my customer complains that (quote)

"Exchange will not let me activate it from CC Desktop app. It's also not in my window => extensions menu anymore either."

So my question is what do I need to put in the "version" attribute inside the "Host" tag in the manifest file to support 14.8? The extension works perfectly fine on my computer where I have Premiere Pro 14.8 installed.
