Samsung Galaxy tab S7 vs Logitech K810 keyboard config conflict

Same question as https://android.stackexchange.com/q/253455/557726 Closed here and go see there for follow up. I have a Galaxy Tab S7 and a Logitech K810 keyboard. I am used to the US-International keyboard configuration, but I am unable to impose it via any means. I tried Logitech apps, Samsung apps, third-party keyboard apps and it just won't stick. The main writing software is google docs, but any writing doesn't keep the US-International configuration, if it even allows me to choose it. Also I am not competent enough to write an app myself.
