Is the antigen test recognised for Ibiza (not the PCR)

Hi.  Wanting to know if the antigen natural flow test is acceptable in Ibiza, as know it was originally only the PCR test, but conflicting answers on different sites.  Seems like now it could be ok to just use the antigen natural flow.  Advice from anyone using this test would be so grateful as cannot take the PCR due to nasal problems.  Also if once tested and confirmation sent -  is it straight forward at the airport or much hassle?  Many thanks.
