Question About Playing EA SPORTS FC™ 25 on My Account Using Another Account

I hope this message finds you well. I currently have the Showcase version of EA SPORTS FC™ 25 linked to my account. I am considering purchasing or using another account that already owns the full version of the game.

Could you please clarify if I will be able to:

Access and play the full version of the game on my personal account while the full version is owned by another account on the same console?
Retain my progress and data from the Showcase version on my personal account if I play using the full version?
Your assistance with this matter would be greatly appreciated. Please let me know if you need further information to assist me.

Best regards,
