[Need advice] Chance of admission for MSc EE with No Maths ECTS

Hello everyone, I graduated BS electrical and electronics engineering in my home country, and I am currently planning to study MSc electrical engineering in Germany. My issue is I don't have any mathematics credits to meet MSc academic requirements.

My case is quite rare so i want to elaborate.

I transferred to my BS EE program as a third year student after completing my second year in a different subject (unrelated to engineering). As part of the transfer process, I passed a math exam by self-studying math, including calculus, linear algebra, and differential equations. This is how it works to transfer to another university in my country. So I did really studied maths on my own, but without formal credit on my transcript. Of course, it is written in my uni's transfer guidelines that transfer students have to pass math exams, but i don't think it will be regarded as an official document and have any effect on my admission process.

I've seen some threads and comments where people said they got math credits recognised from subjects that involve mathematics. So if this is true and applicable to me, I have taken several math-based courses: Automatic Control (where linear algebra and differential equations are essential), Signals & Systems (calculus, complex numbers, etc.), Electromagnetic Fields and Waves, and so on. Also, I earned 125 ECTS over two years (75 credits in my country) along with admitted 116 ECTS recognised from the previous university. (Total: 241 ECTS).

My questions:

1. is there any chance to get recognised maths credits from other relevant courses?

2. what should I do in my situation?

I would appreciate any comments from all of you.

For additional information, if it helps you give me advice:
