How do i set a song in apple music as the ring tone for a specific contact in my iphone se ios 16.4

I want to set a song from Apple Music as the ringtone for a specific contact, but am unable to.

To make and/or use a song as a ringtone, you must first make that song suitable for a ringtone.

See the following Apple articles:

Create and manage ringtones -> Create and manage ringtones - Apple Community

Create a ringtone of your Logic Pro or GarageBand for Mac song

Create a ringtone of your Logic Pro or GarageBand for Mac song – Apple Support (UK)

Create Ringtones in Garageband -> Create Ringtones in Garageband - Apple Community

I have also purchased a ring tone (Same song as I want from Music) from the iTunes store.
