The local environments of fast radio bursts (FRBs) hold valuable clues about their physical origins. There are two FRBs known that are associated with compact persistent radio sources (PRS), hypothesised to be surrounding nebulae. The origin of both FRBs and PRSs are debated within the community. The discovery of more PRSs at even closer distances, will allow us to further probe both radio sources mysterious origins. Using scintillation measurements of FRB 20221022A, we have uncovered that this FRB is embedded within a nebula or supernova remnant (Nimmo et al., in prep). FRB 20221022A is therefore an incredibly promising candidate for an associated PRS. We propose to search the nearby host galaxy of FRB 20221022A for a PRS, which would give insights into the mysterious origins of the PRS emission, their links to the FRB source, and uncover a diversity in the PRS emission that has not yet been observed. Furthermore, this can inform future search strategies for PRSs.
