Working remotely from another country as a regular, non freelancer, employee

I work remotely for a company based in Israel as a regular staff employee. All the taxes are deducted from my paycheck. Since I can work remotely, I would love to stay in Spain or Portugal on the digital nomad visa. The problem is they also want some taxes. But If I pay in both countries I am left with 40 percent of the salary. I know there are tax treaties between Israel and Spain, does it help in my situation?
