Is there a way that I can make this mod to be able to be used in the Endseige mod? if so plz let me know.

Support for other mods isn't going to be coming any time soon, however you should be able to do everything you need to make an Endseig add-on right now.

Apart from some of the Endseig states not being available in the base game's map (e.g. the split between East/West Germany) everything should be doable. All of the states you have selected for your current nation shouldn't conflict with the mod either. (It is mainly Europe & Middle East which have different states)

The one thing you will need to add though is all of the endseig ideologies, so your country can use it. If you create an ideology for each of the ideology types in game (e.g. Paternal Autocrat) and import the mod's corresponding ideologies in, you can then assign them to any custom nation(s) you want to add.

Im like very new to Modding if u want to chat more u can add me on Discord if u want I need alot of help im trying to figure out aswell how to make were I can have national focus for Industry and stuff and have them give u ware goals on a serton country for example my country that im making takes place in America and i want to be able have a focus that gives me a annex war goal on America.

and how u male a custom Ideology bee used for ur country cant get the one I made to work.

If you created the ideologies after the country, this post should help: https://edge.hoi4modding.com/forum/suggestions/868-custom-ideologies-and-country#2346

If you created the ideologies before the country, they should be added automatically.

Thx another thing what about the event I cant get them to trigger Iv made some but they wont trigger I must be putting a piece of code in wrong.
