37. Finally, concerning the other formulas:
1. Some constitute an independent rite or act, such as the Gloria, the responsorial Psalm, the Alleluia and verse before the Gospel, the Sanctus, the Memorial Acclamation, and the cantus post Communionem (song after Communion)[rendered as "chant" in my print copy of revised GIRM];
2. Others accompany another rite, such as the chants at the Entrance, at the Offertory, at the fraction (Agnus Dei), and at Communion.
88. When the distribution of Communion is finished, as circumstances suggest, the priest and faithful spend some time praying privately. If desired, a psalm or other canticle of praise or a hymn may also be sung by the entire congregation.
37. Demum ex aliis formulis:
1. nonnullae ritum seu actum per se stantem, uti hymnus Glória, psalmus responsorius, Allelúia et versus ante Evangelium, Sanctus, acclamatio anamneseos, cantus post Communionem, constituunt;
2. nonnullae vero, uti cantus ad introitum, ad offertorium, ad fractionem (Agnus Dei) et ad Communionem, ritum aliquem comitantur.
88. Distributione Communionis expleta, pro opportunitate sacerdos et fideles per aliquod temporis spatium secreto orant. Si placet, etiam psalmus vel aliud laudis canticum vel hymnus a tota congregatione persolvi potest.
Perhaps I answered the question for myself
