D&D5e Warlock Spell slot level with the feat Metamagic Adept from Tasha’s Cauldren of Everything

I have a warlock tiefling for which I am considering to choose the feat Metamagic Adept from Tasha’s Cauldren of Everything. This will get me 2 sorcery points to spend.

  1. Looking at the sorcery point system I believe I could spend these 2 sorcery points to regain one 1st-level spell slot, since a warlock only has a few this. I imagine this would be helpful. However this is not stated in the feat specifically, only to use two Metamagic options. Is there a source that mentions something about the feat that one could exchange the 2 sorcery points into spell slots as well? Or would someone rule it as possible?

  2. If I understand correctly, as a warlock I could only cast spells at a certain level. The reason I am asking is related to the question above. If I am returning 2 sorcery points and get a 1st-level spell back. That would be great at lower levels I think. Since a warlock as of 3rd level could only cast spells from level 2, a warlock starting from level 5 casting level 3 spells, etc. Meaning I (most likely) wouldn’t prepare a 1st level spell at higher levels. Could I exchange 2 sorcery points for a 1st level spell, but then cast it at a higher level spell since I am a warlock, or is that the reason why the answer to question 1 would be no?

Below the information on sorcery points (flexible casting) and the feat metamagic adept.

Feat Metamagic Adept:

You’ve learned how to exert your will on your spells to alter how they function. You gain the following benefits:

  • You learn two Metamagic options of your choice from the sorcerer class. You can use only one Metamagic option on a spell when you cast it, unless the option says otherwise. Whenever you gain a level, you can replace one of your Metamagic options with another one from the sorcerer class.
  • You gain 2 sorcery points to spend on Metamagic (these points are added to any sorcery points you have from another source but can be used only on Metamagic). You regain all spent sorcery points when you finish a long rest.

Flexible Casting:

You can use your sorcery points to gain additional Spell Slots, or sacrifice Spell Slots to gain additional sorcery points. Creating Spell Slots. You can transform unexpended sorcery points into one spell slot as a Bonus Action on Your Turn. The created Spell Slots Vanish at the end of a Long Rest. The Creating Spell Slots table shows the cost of Creating a Spell slot of a given level. You can create Spell Slots no higher in level than 5th. Any spell slot you create with this feature vanishes when you finish a Long Rest.
