does/should it work with python <3.8?

[DJCrashdummy]

beforehand: i wrongly posted this issue already at a different project (TheAssassin/kodi-invidious-plugin#18)... sorry for somehow assuming - just because of the same addon id - that these two projects are closer related.

---

i'm using the latest OSMC (2022.03-1) which provides Kodi 19.4 and is based on Debian 10 Buster. the addon plugin.video.invidious from the official repo (0.1.0+matrix.1) can be installed, but if i try to send any request to the chosen invidious instance - no mater which one - i get a 403 response.
because it seems a little bit outdated, i activated/installed @lekma's addon repo, installed it's latest version (1.0.10), but then i just get an error notification to look at the logs for further information... the lines invidious related:

it seems that this addon - at least all version in @lekma's addon repo - uses/assumes python 3.8 but Debian Buster provides only python 3.7 (3.7.3-1 in my case to be precise).

if i'm correct, is there any chance to get this addon working with python <3.8 (with reasonable effort)? or is there a way to install the needed dependencies resp. check them beforehand and avoid installing/updating if they are not met?

Worth noting that Debian 11 (Bullseye) ships with Python 3.9 already, and Debian 12 (Bookworm) which comes out on June 10th 2023 will ship with Python 3.11.

In May 2022, OSMC announced that they'd release test builds using Debian 11, which should've resolved the issue.

Two days after this issue was made, that version of OSMC got it's official release. 🎉 [source]

If this is the only problem, it looks like it'd be a small change to gain Python 3.7 support for those that are stuck with that for whatever reason. But an alternative solution is to just install a version of OSMC of 2022.09-1 or more recent.

Could be worth closing this. 🤔
