Using interrail to get from UK to europe

Hi everyone, I’m currently trying to figure out what would be more viable to get from the U.K. to Amsterdam. I’ve looked at the global pass for 5 days, as we will be travelling via train into Amsterdam from just outside it most days. Can the global pass be used to get to london from elsewhere in the UK, catch the Eurostar, and get to our accommodation just outside Amsterdam, and then do the reverse on the way back (provided we have the necessary amount of travel days left to use)? Given we’ll be travelling via train most of the time there anyway it seems like a pass might be more budget friendly than getting a flight there and back then buying train tickets every day.
