National Insurance contributions in EEA previous to Brexit

I am a spanish national living in UK since 2010 with permanent settlement status. In order to reach the minimum qualifiying years requirement for the State Pension (30), I would like to apply for the years previously contributed to the Spanish National Insurance. If I am not wrong, before Brexit, there was an agreement to recognize the full lenght of contributions in any EEA member. Is it possible?
